Brief plan for updating Mozilla Firefox

Source:Install Firefox on Linux - "Install Firefox .deb package for Debian-based distrIbutions "(EN) or Installation .deb package FIrefox для основанных на Debian Distributions (recommended) (Rus).

Firefox update consists of four stages:

• Import of the Mozilla repository key using WGET and GPG
• Adding a SOU type filerce-list для репозитория Mozilla PPA в систему, в папку /etc/apt/sources.list.d
• Installation of priority PPA Mozilla over the full -time repository
• Package updateapt-get update

To change the inscriptions in Firefox of the latest version into Russian:

• Removing the old package language pack - файла руссификации (перевода на русский язык) предыдущей версии
• Installation of a new package language pack - файла руссификации (перевода на русский язык) текущей версии
• Switching the tongue in the program.

Detailed description of Mozill updatea Firefox

1) Creation of a directory /etc/apt/keyrings (если не существует), назначение ей прав доступа

ls -ld /etc/apt/keyrINGS

If the directory exists, we check the attributes.
Line drwxr-xr-x 2 root root , означает что права владельца root - rwx (7), группы root - r-x (5), остальным r-x (5), i.e. 755

• Rights are established correctly.

• If the catalog /etc /apt/keyrINGS does not exist, we create it with one team with the right rights

  sudo install -d -m 0755 /etc/apt/keyrINGS

• If the rights do not match Drwxr-xr-x, задаём их с помощью chmOD

  sudo chmod -R 0755 /etc/apt/keyrINGS

2) Add to the operational system of the repository key. The import of the key signed by the PPA-Ro-Poposior Mozilla

wget -q https://packages.mozilla.org/apt/repo-signing-key.gpg -O- | sudo tee /etc/apt/keyrings/packages.mozilla.org.asc > /dev/Null

(If WGET is not installed, it can be installed with a command sudo apt install wget).

3) Checking the repository key. Its imprint should correspond to 35baa0b33e9b396f59CA838C0BA5CE6DC6315A3

gpg -n -q --import --import-options import-show /etc/apt/keyrings/packages.mozilla.org.asc | awk '/pub/{getline; gsub(/^ +| +$/,""); if($0 == "35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3") print "\nThe key fingerprint matches ("$0 ").\n"; else print "\nVerification failed: the fingerprint ("$0 ") does not maTch The Expieded One. \ N "} '

4) Now add a text file mozilla.list в каталог /etc/apt/sources.list.d с описанием PPA-репозитория Mozilla

echo "deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main" | sudo tee -a /etc/apt/sources.list.d/mozilla.list > /dev/Null

The contents of the file can be viewed by the command:

cat /etc/apt/sources.list.d/mozilla.List

It must contain one line
deb [signed-by=/etc/apt/keyrings/packages.mozilla.org.asc] https://packages.mozilla.org/apt mozilla main

5) APT configuration to increase the priority of the new Apt Mozilla repository before the system repository of the operating system

echo '
PackaGE: *
Pin: origin packages.mozilla.orG
Pin-Priorit: 1000
' | sudo tee /etc/apt/preferences.d/mozilla 

If you do not take this step, the update for our Firefox package will not be found.

View the contents of the filemozilla в каталоге preferEnces can be a team. It should be like this:

cat /etc/apt/preferences.d/mozilla 

P.ackaGE: *
PIN: Origin packages.mozilla.orG
Pin-Priority: 1000

6) updating the packet cache and installing the latest version of the Firefox browser

sudo apt-get update && sudo apt-get install firEfox -y

7) Before installing a new Russification file, you need to delete the Russian language package (language pack) the old version (128).
