De-Googling my phone Xiaomi Poco F1 with LineageOS 17.1 ROM

De-Googling Xiaomi Poco F1 is very simple, only need 4 steps:

  1. Unlock phone (MIUI Unlock)
  2. Download software
  3. Install Custom Bootloader (LineageOS Recovery image)
  4. Flash ROM (LineageOS+NanoDroid)


1. Unlock phone (MIUI Unlock)

Pocho F1 comming with MIUI Android derivate. First let MIUI make all updates, and if don't have Mi Account make and sign in. Wait about 3 days to give permission for unlock phone. Now download software for unlock (running on windows - work on linux over kvm or virtualbox) and shutdown phone. Start program as Administratorm next hold Volume Down & Power on phone to enter in fastboot and connect phone with usb cabel on PC and click Unlock.


2. Download Software

First I download files from and :

  1. Boot Recovery: lineage-17.1-20200725-recovery-beryllium.img
  2. LineageOS 17.1 ROM:
  3. NanoDroid-microG:
  4. NanoDroid-fdroid:


3. Install Custom Bootloader

I try recovery image from LineageOS and work nice, but if wont to use twrp is don't have any limit to use. In my example I will use recovery image from LineageOS.

With the device powered off (connect phone with pc-usb cabel ). With the device powered off, hold Volume Down + Power. Keep holding both buttons until the “POCO” logo appears on the screen, then release.

Start flash with:

fastboot flash recovery lineage-17.1-20200725-recovery-beryllium.img

Note: Some PC have problems with USB3, try connect phone on USB2.


4. Flash ROM (LineageOS+NanoDroid)

Now powered off phone, then hold Volume Up + Power. Keep holding both buttons until the “POCO” logo appears on the screen, then release.

Now tap Factory Reset, then Format data / factory reset and continue with the formatting process. This will remove encryption and delete all files stored in the internal storage, as well as format your cache partition (if you have one). Return to the main menu, then select “Apply Update”, then “Apply from ADB” to begin sideload.

On PC with adb tools import image of LineageOS:

adb sideload

Then import images NanoDroid-microG & NanoDroid-fdroid:

adb sideload
adb sideload

Once you have installed everything successfully, click the back arrow in the top left of the screen, then “Reboot system now”.

Now enjoy in Poco F1 LineageOS 17.1 without Google services but have F-Droid for FOSS application and Aurora store (if need aplication from google store).

How to up Nextcloud 19 server on Debian 10 Buster in 10 min

Before start please check system requirements for Nextcloud 19 server.

In my guide I using Debian 10 (Buster) GNU/Linux for OS.


1. Choice of Database

First need choice database for Your Nextcloud. Depend of Your need.

If just wont to try/test Nextcloud You can to use SQLite, alternative to SQLite if don't have big number of users good choice is MariaDB but in time from my experience number of user will go up and my choice is PostgreSQL.

Database is very important and Debian 10 (Buster) comming with PostgreSQL 11, but for better performance I using PostgreSQL 12 from repository pgdg.

* If will use SQLite please ignore instructions about PostgreSQL.


Add PostgreSQL 12 Repository & install package:

echo 'deb buster-pgdg main' >> /etc/apt/sources.list.d/pgdg.list
wget --no-check-certificate -q -O- | apt-key add -
apt-get update
apt-get install postgresql-12

Create new user & database for Nextcloud:

su - postgres
CREATE USER ncuser WITH PASSWORD 'StorngPasswordHere';

Now Your database is ready for use.


2. Add repository Jurisic and install package nextcloud-server

echo 'deb buster main contrib non-free' >> /etc/apt/sources.list.d/jurisic.list
wget -q -O- | apt-key add -
apt-get update
apt-get install nextcloud-server


3. Configure Apache2 service (Virtual Host, SSL Certificate)

If using friesh installed Debian, package nextcloud-server will install apache2 and php packages.

Default Apache config will configure working url at links http://<ip address>/nextcloud or http://<hostname>/nextcloud

First we need enable support for ssl and that is very easy:

a2enmod ssl
a2ensite default-ssl
systemctl restart apache2

After enable Apache module ssl and site default-ssl we have self signed certificate at links https://<ip address>/nextcloud or https://<hostname>/nextcloud and its You fine with links no need more adjust Apache.

But for example I buy domain and wont to run nextcloud at link, here instruction what need to add in Apache.

Open text editor with:

nano /etc/apache2/sites-available/

Make file:

<VirtualHost *:80>
        DocumentRoot /var/www/nextcloud

        Redirect permanent /

        ErrorLog ${APACHE_LOG_DIR}/nextcloud_error.log
        CustomLog ${APACHE_LOG_DIR}/nextcloud_access.log combined


<IfModule mod_ssl.c>

<VirtualHost _default_:443>
        DocumentRoot /var/www/nextcloud

        <Directory "/var/www/nextcloud">
            Options +FollowSymLinks
            AllowOverride All

            <IfModule mod_dav.c>
                Dav off

            SetEnv HOME /var/www/nextcloud
            SetEnv HTTP_HOME /var/www/nextcloud

        <Directory "/var/www/nextcloud/data">
            Require all denied

         <IfModule mod_headers.c>
            Header always set Strict-Transport-Security "max-age=15552000; includeSubDomains; preload"

        <IfModule mod_php7.c>
            <IfModule mod_env.c>
                SetEnv htaccessWorking true

        ErrorLog ${APACHE_LOG_DIR}/nextcloud_error.log
        CustomLog ${APACHE_LOG_DIR}/nextcloud_access.log combined

        SSLCertificateFile      /etc/ssl/certs/ssl-cert-snakeoil.pem
        SSLCertificateKeyFile /etc/ssl/private/ssl-cert-snakeoil.key


Now disable stadard site and enable new with:

a2dissite 000-default
a2dissite default-ssl

Now is good time for setup ssl certificate. We can to use any solution or use free service Let's Encrypt.

Easy way to create and activate ssl certificate with Certbot:

apt-get install certbot python-certbot-apache
certbot --apache


4. Configure PHP (php.ini)

Settings for PHP can simple change. Just open file /etc/php/7.3/apache2/php.ini :

nano /etc/php/7.3/apache2/php.ini

Find keys and change value:

upload_max_filesize = 512M
post_max_size = 512M
memory_limit = 512M
mbstring.func_overload = 0
default_charset = "UTF-8"
output_buffering = 0


5. Optional configure PHP-FPM (Fast/CGI) instead default PHP

Switch Apache to event mode and enable fcgid:

a2dismod php7.3
a2dismod mpm_prefork
a2enmod mpm_event
a2enmod proxy_fcgi

Install package php-fpm :

apt-get install php-fpm
a2enconf php7.3-fpm
systemctl restart apache2 php7.3-fpm

Settings for PHP-FPM can simple change. Just open file /etc/php/7.3/fpm/php.ini :

nano /etc/php/7.3/fpm/php.ini

Find keys and change value:

upload_max_filesize = 512M
post_max_size = 512M
memory_limit = 512M
mbstring.func_overload = 0
default_charset = "UTF-8"
output_buffering = 0

Check great article about PHP FPM - optimization.

Example of my configuration (Note: PC have 8 CPU core, 8 Gb of RAM:):

Adjusted StartServers, MaxRequestWorkers and MaxConnectionsPerChild:

nano /etc/apache2/mods-enabled/mpm_event.conf

Example of file:

<IfModule mpm_event_module>
        StartServers            8
        MinSpareThreads         25
        MaxSpareThreads         75
        ThreadLimit             64
        ThreadsPerChild         25
        MaxRequestWorkers       248
        MaxConnectionsPerChild  1000

Adjusted PHP-FPM pool:

nano /etc/php/7.3/fpm/pool.d/www.conf

Changed variables:

pm = dynamic
pm.max_children = 400
pm.start_servers = 32
pm.min_spare_servers = 16
pm.max_spare_servers = 32
pm.max_requests = 1000

Restart services :

systemctl restart apache2 php7.3-fpm


6. Optional configure memory caching

Good idea is to setup memory caching. If you have enough memory, use APCu for Memory Caching and Redis for File Locking.


6.1 For PHP APCu first need to install package and restart services:

apt-get install php-apcu
systemctl restart apache2 php7.3-fpm


6.2 Install Redis server and configure for work over unix socket:

apt-get install redis-server php-redis

Adjusted Redis server:

Enable unixsocket

nano /etc/redis/redis.conf

Find in file unixsocket and uncomment lines (note: change permission from 700 to 770):

unixsocket /var/run/redis/redis-server.sock
unixsocketperm 770

Change somaxconn and overcommit:

nano /etc/sysctl.d/40-redis-server.conf

Add in new file:

net.core.somaxconn = 1024
vm.overcommit_memory = 1

Transparent Huge Pages (THP) support disable:

nano /etc/default/grub



Then apply changes with:


Reboot server:

systemctrl reboot


7. Web install of Nextcloud

Now is server ready for Nextcloud web installation, open url: or (depend how You configure Your Apache2)

Create admin account (username,password), configure database (click on PostgreSQL,username,password,database) and click "Finish setup":


8. Optional enable cache in config file of Nextcloud

Check section 6.1 and 6.2. If wont enable cache by PHP APCu and Redis server:

nano /var/www/nextcloud/config/config.php

Add in config:

  'memcache.local' => '\\OC\\Memcache\\APCu',
  'memcache.locking' => '\\OC\\Memcache\\Redis',
  'memcache.distributed' => '\\OC\\Memcache\\Redis',
  'redis' =>
  array (
    'host' => '/var/run/redis/redis-server.sock',
    'port' => 0,
    'timeout' => 0,
    'password' => '',
    'dbindex' => 0,


Congratulations and enjoy in Nextcloud !!!

Nextcloud server on Debian 11 Bullseye

I build nextcloud-server package for three Debian release (stretch, buster and bullseye).

Steps for install:

1. Install database (in my example I use PostgreSQL):

apt-get install postgresql

2. Create database,user on database:

su - postgres
CREATE USER nextuser WITH PASSWORD 'HereSomeGoodPassword';

3. Add repository & keyring:

echo 'deb bullseye main contrib non-free' >> /etc/apt/sources.list.d/jurisic.list
wget -q -O- | apt-key add -
apt-get install nextcloud-server

4. Enable ssl for apache2:

The default installation of Nextcloud is not secured by SSL. To enable SSL in your webserver, run these commands:

a2enmod ssl
a2ensite default-ssl
service apache2 restart

You will probably get a SSL warning, this warning should be accepted. To avoid such warnings, get a free signed SSL certificate from LetsEncrypt.

5. Nextcloud web installer:

When the shell part of the installation is finished, proceed by opening the Nextcloud web installer in your browser. The URL is http://[YOURIP]/nextcloud

Enter the desired administrator username and password in the login fields. Please choose a secure password and also a username that is not "admin" or "administrator" might be a good choice to make it less easy for attackers to guess your admin login.

Nextcloud is using sqlite as storage engine by default. This is not a good choice performace wise, so I will choose PostgreSQL as database backend. We have created a PostgreSQL database above, enter the details of that database now:

  • Username:         nextuser
  • Password:          The password that you have choosen for the database.
  • Database name: nextcloud
  • Hostname:         localhost

Then click on the button to finish the installation. You will get greeted with a welcome screen.

Rebuild Debian repository for Debian Stretch (oldstable) and Buster(stable)






Today I rebuild Debian repository for Debian Stretch (oldstable) and Buster(stable), in new repositroy is included:

  • binary package
  • orginal source package
  • debian build package
  • file describes a source package

Think this repository needs to be more transparent and open to collaboration and for that reason git repository will be available soon where you will be able to contribute.

Debian 9 Stretch in own package for php use version 7.0.33 and Nextcloud 15 work because it does not require a newer version of php. End of life for Nextcloud 15 comming in 2019-12. It is strong recommended to upgrade on Debian 10 Buster in this month.

I build package for Debian 10 Buster and atm. work with Nextcloud 17, table of supported versions by release of Debian:

Package Debian Release Version
nextcloud-server Stretch 15.0.13
nextcloud-server Buster 17.0.1

Before any action (Upgrade OS or Nextloud) make backup of Nextcloud server. I'm not responsible for interruption of work or loss of data. Backup can save lot time and data. Check documentation on:

Best way is new clean installation of Debian 10 (buster) and install nextcloud-server package from .

Setting up Samba as an Active Directory Domain Controller on Debian 9 Stretch


Samba is great project and if wont make Samba AD DC today is very simple. More about Samba look at

Preparing the Installation

  • select hostname(,domain name(
  • installation and configure of time server (ntp)
  • installation and configure of domain name system (bind9)


Set hostname of my Samba ad dc server:

hostnamectl set-hostname

Edit hosts:

nano /etc/hosts dc1

Installation and configure of time server (ntp):

apt-get install ntp

Change settings in ntp.conf

nano /etc/ntp.conf

logfile   /var/log/ntp.log
driftfile /var/lib/ntp/ntp.drift
ntpsigndsocket /var/lib/samba/ntp_signd/

pool iburst
pool iburst
pool iburst
pool iburst

restrict -4 default kod notrap nomodify nopeer noquery limited
restrict source notrap nomodify noquery
restrict default kod nomodify notrap nopeer mssntp

Fix bug apparmor (Thanks to  Louis van Belle):

Enable the local file part for ntpd:

sed -i 's[#include <local/usr.sbin.ntpd>[include <local/usr.sbin.ntpd>[g' /etc/apparmor.d/usr.sbin.ntpd

NTPD fix.:

echo "
  # To sign replies to MS-SNTP clients by the smbd daemon /var/lib/samba
  /var/lib/samba/ntp_signd r,
  /var/lib/samba/ntp_signd/{,*} rw,

  # samba4 winbindd pipe
  /{,var/}run/samba/winbindd r,
  /{,var/}run/samba/winbindd/pipe rw,

  # samba4 winbindd privileged pipe ? Needed?
  /var/lib/samba/winbindd r,
  /var/lib/samba/winbindd/pipe rw,

" >> /etc/apparmor.d/local/usr.sbin.ntpd

Installation and configure of domain name system (bind9):

Instalirati bind9 paket:

apt-get install bind9

Configure neamed.conf.options

nano /etc/bind/named.conf.options

//  Add any subnets or hosts you want to allow to use this DNS server
acl internal {;;

options {

        auth-nxdomain yes;
        directory "/var/cache/bind";
        notify no;
        empty-zones-enable no;
        listen-on-v6 { none; };

        forwarders {

        allow-query { internal; };
        allow-recursion { internal; };
        allow-transfer { none; };

Finale step start service and test ntp and bind9:

systemctl restart ntp.service bind9.service

Set in resolv.conf our bind9:

nano /etc/resolv.conf


Now test bind9:

Test the localhost forward zone):

host -t A localhost 

Default respond is:

Using domain server:

localhost has address

To test the reverse zone:

host -t PTR 

Default respond is:

Using domain server:
Aliases: domain name pointer localhost.

Test NTP server:

ntpdate -q

Default respond is:

server, stratum 2, offset -0.000073, delay 0.02602
24 Apr 12:10:30 ntpdate[10143]: adjust time server offset -0.000073 sec


Installing Kerberos & Samba and configure Bind9 with Samba:

  • Installing Kerberos and configure
  • Installing Samba and configure
  • Configure Bind9 to work with Samba

Installing Kerberos and configure:

apt-get install krb5-config krb5-user

Configure krb5.conf

nano /etc/krb5.conf

        default_realm = INTERNAL.EXAMPLE.COM
        dns_lookup_realm = false
        dns_lookup_kdc = true


Installing Samba and configure:

Debian bring Samba 4.5.16 but that version don't have JSON module (Need 4.7+ for JSON), and I find great repository by Louis van Belle (Please feel to free Donate to Louis).

Add repos:

wget -O - | apt-key add -

echo "# AptVanBelle repo for samba." | sudo tee /etc/apt/sources.list.d/van-belle.list

echo "deb stretch-samba410 main contrib non-free" | sudo tee -a /etc/apt/sources.list.d/van-belle.list

apt-get update

Install samba:

apt-get install samba winbind attr acl

Configure service samba for AD DC:

systemctl stop smbd nmbd winbind
systemctl mask smbd nmbd winbind
systemctl disable smbd nmbd winbind
systemctl unmask samba-ad-dc
systemctl enable samba-ad-dc
systemctl daemon-reload

Configure Samba as AD DC:

If exist old configuration of samba /etc/samba/smb.conf then make backup of config and delete.

cp /etc/samba/smb.conf /etc/samba/smb.conf.bck
rm /etc/samba/smb.conf

samba-tool domain provision --use-rfc2307 --realm INTERNAL.EXAMPLE.COM --domain EXAMPLE --server-role dc --dns-backend=BIND9_DLZ  --adminpass StrongPassword

Configure Bind9 to work with Samba:

Add under section options { }

nano /etc/bind/named.conf.options

allow-update {; };

// DNS dynamic updates via Kerberos (optional, but recommended)
//tkey-gssapi-keytab "/var/lib/samba/private/dns.keytab";    //samba 4.8 and lower
tkey-gssapi-keytab "/var/lib/samba/bind-dns/dns.keytab";    // samba 4.9 and up


Add rndc.key, bind-dns include in named.conf
