Transition to Linux Mint 21.2

1) in the "Update Manager" - "View" - "Linux nucleus" I deleted the core 5.19, left 5.15 (will be used when loading the default PC)
2) in the catalog /etc /apt/sources.list.d убрал файлы конфигурации сторонних репозиториев (я создал папку bak и заархивировал в неё файлы *.list
3) In the program "Application Sources" disabled all PPA-re-repositories.
4) in the "Update Manager" switched to local mirrors in the Russian Federation
5) completely updated the programs in the Sudo terminalapt-get update && sudo apt-get upgrade && sudo apt-get autoremove && sudo apt-get autoclean
6) We need a package for updatingmint-upgrade-info (был установлен) sudo apt install mint-upgraDe-info
7) rebooted the PC (now the kernel 5.15)
8) in Timeshift created a picture of the system in case of unforeseen circumstances when updating
9) in the "Update Manager" - "Edit" performed the action "update to Linux Mint 21.2 Victoria"
10) After the update ended, the PC rebooted. The version of the operating system instead of 21.1 became 21.2.
11) in the "sources of applications" switched to local mirrors in Russia (because they automatically switched to others).

Features of the transition

In the "Update Manager" before the transition, you need to remove the checkmarks against 5 FL programsatPak (org.freedesktop.platform ...) и KDE (org.kde.Plarform ...) и VAAPI.
After the transition to 21.2, in the "Update Manager" you need to again switch to Linux Mint local mirrors in the Russian Federation

Famous problems and errors

If on computers with UEFI there are no launching and installation of OS with ISO flash drive, you need to disconnect the Secureboot option in the BIOS Setup
If the transition is not made, but a clean installation from the flash drive, error g is possiblerub "Out of memory ". To solve the problem, you need to prepare a boot USB disk using rufus
After the update, I noticed that some of the screen guardians (Badalloc error) do not work, the work of which is associated with OpenGL
If you use 2k монитор, и иконки выглядят мелкими, нужно установить пакет sudo apt install grub2-theme-mint-2k
The program "Systems reports" discovers in the system tray a conflicting indicatorayatana-indicator-applicaTion (I recommend deleting it)
Linux Mint has the ability to hack a system through SNap (который хотя и отключен, но может быть установлен через зависимости пакетов): "Некоторые пакеты APT в репозиториях Ubuntu не только устанавливают snap как зависимость, но также запускают команды snap от имени root без вашего ведома или согласия и подключают ваш компьютер к удаленному проприетарному хранилищу, управляемому Canonical." Таким образом, необходимо контролировать отсутствие магазина snaP the command

sudo apt purge snaP* -y
The program for working with evolution e -mail is not launched. Error "Badalloc".

(Evolution: 4195): GDk-ERROR **: 16:05:10.647: The program 'evolution' received an X Window System error. This probably reflects a bug in the program. The E.rror was 'BadAlloc (insufficient resources for operaTion) '. (Details: serial 193 error_code 11 request_code 149 (unknown) minor_code 2) ### Solving the problem of starting Evolution The problem was related to the _ replacement of the video card_ built -in Intel on the ATI Radeon X300. #### Solutions: In the catalog /etc/x11/xorg.conf.d deleted the old file from the built -in Intel graphics sudo rm /etc/X11/xorg.conf.d/20-intel.conf ATI R video card driveradeon подключается к ядру автоматически, ничего делать не нужно. Можно, но не обязательно, выполнить команду "sudo update-initramfs -u" для активного ядра (которое запускается по умолчанию при следующей загрузке) или "sudo update-initramfs -u -k aLL " for all nuclei of the OS (for example, backup, such as 5.10). sudo apt update sudo apt upgrade sudo apt install initramFS-TOOLS sudo update-initramfs -u -k aLL I completed the reboot and in recovery mode (text mode without graphics) completed the next command on behalf of "Root": X -configure In the output of the window there should be information about the video card. In my caseraDeon in the amount of 2 pcs. - Since the video card has 2 outputs of the video for 2 monitors. Copying the configuration: sudo cp /root/xorg.conf.new /etc/X11/xorG.Conf Reboot the computer. reboot After entering the desktop, the launch of the Evolution mail client occurs without error. There is only a small warning:

** (evolution:11018): WARNING **: 16:40:03.878: WEBKIT_FORCE_SANDBOX no longer allows disabling the sandbox. Use WEBKIT_DISABLE_SANDBOX_THIS_IS_DANGEROUS=1 instead.

**Solution:** Perform from the terminal: export WEBKIT_DISABLE_SANDBOX_THIS_IS_DANGEROUS=1 !!!! There are no errors or warnings now. Now the screen keepers began to work (SCreensaver) using Opengl. The main thing is that Evolution works. ![SNakE.](snake.png "snake")
