Update/P11

The update procedure from p10 to p11 is similar to the update to p10.

Upgrade

Attention! The license agreement of the originally installed system remains in effect during the upgrade process.

Note: All the commands in this article require root permissions

Attention! Since the upgrade affects the D-Bus service as well, the upgrade process may cause Xorg to crash. Therefore, it is better to run the distribution upgrade command apt-get dist-upgrade directly in the text console (Ctrl+Alt+F2)

Attention! First read the "Known issues" section at the end of the article.

0. Make a backup of your system before upgrading

Attention! If you are not sure that you can fix the system yourself in case of a failed upgrade, make sure to make a system backup ([ru])!

It is advisable to uninstall all packages you don't need ([ru]), and disable unneeded services ([ru]) before upgrading your system. This will save you some time during the upgrade process, and reduce the traffic of downloaded packages.

Third-party packages that are not in the p10 repository may not be supported by the upgraded system and may interfere with a successful upgrade.

1. Upgrade the distribution to the latest p10

All operations must be done with root user permissions.

# apt-get update
# apt-get dist-upgrade

2. Check apt-repo ([ru])

Most likely the utility has already been installed and updated in the first step, but just in case, check for the following:

# apt-get install apt-repo

3. Change the update sources

Note: The following command will replace all sources in the /etc/apt/sources.list file. If you have third-party repositories defined, make a backup of the file.

# apt-repo set p11

To upgrade from p10 to p11, it is not enough to just change sources. apt-repo does everything necessary: in addition to changing sources, it creates a file /etc/rpm/macros.d/priority_distbranch with the following contents:

%_priority_distbranch p11

4. Upgrade to p11

Attention! Since the upgrade affects the D-Bus service as well, the upgrade process may cause Xorg to crash. Therefore, it is better to run the distribution upgrade command apt-get dist-upgrade directly in the text console (press Ctrl+Alt+F2, enter root and your root user password).

Note: You can use screen or tmux. In this case, a crash of xorg should not cause the console running the upgrade procedure to close, and it can be reconnected from the text console accessible from Ctrl+Alt+F2.On a system with systemd, pre-install the systemd-settings-disable-kill-user-processes package, restart the systemd-logind service and log in (re-login) again.

# apt-get update

Note: Optional step:

# apt-get clean
# apt-get dist-upgrade -d

The first command will remove all old packages from the apt cache, the second will download (but not install) all the packages you need. If you have already downloaded something new, it may be advantageous to use autoclean instead of clean. The resulting contents of /var/cache/apt can be used for a subsequent bulk installation of packages via rpm in case of upgrade problems.

Attention! On systems using SecureBoot, it is mandatory to update the kernel with the update-kernel command before rebooting. Otherwise, the system may become unbootable!

Perform the actual upgrade:

# apt-get dist-upgrade
# update-kernel

If at the end of the upgrade it says

E: Transaction errors occurred

run

# apt-get -f install
# apt-get dist-upgrade

5. Reboot

Attention! On systems using SecureBoot, it is mandatory to update the kernel with the update-kernel command before rebooting. Otherwise the system may become unbootable!

Reboot the system.

6. Removing obsolete packages

Use the tips at APT in ALT Linux/Tips for using ([ru]) to remove obsolete packages.

Upgrade via EPM

You can upgrade from p10 to p11 using the epm program by first installing the latest version:

# apt-get install eepm 

and then commanding:

# epm release-upgrade

Attention! It is recommended to run the remote update either through a screen or tmux session (but even in these you will get a relogin warning and things won't go any further), or with --force --auto — with no guarantee of successful completion. So it's better to do it from the physical console.

Next, update the kernel:

# update-kernel

Remove obsolete packages with the command:

# epm autoremove --direct

The program will perform all necessary actions for the upgrade, including the commands described above in the manual upgrade order.
