Mageia forum

Hello,
I have tried to update mageia 7, but ran into problems.

The method used to begin update was Upgrading online, using mgaonline (GUI) https://wiki.mageia.org/en/Mageia_8_Rel ... _.28GUI.29

Code: Select all

su -c 'mgaapplet-upgrade-helper --new_distro_version=8'

Unfortunately, the lock screen trapped me twice. The first time, I managed to recover control thanks command:

Code: Select all

loginctl unlock-session c5

So after a few minutes, without a GUI, I switched to a virtual terminal tty to check what's going on. As the repositories were bound to mageia 8, I ran the

Code: Select all

urpmi --auto-update

command. Which has installed a large number of packages, but at the end of the list a lack of space interrupted the process.
...
A restart showed a screen initiation where the keyboard was not responding. In the center of the screen, three gray question marks were successively changing to white. After a while, I rebooted for a rescue mode. The latter is more verbose. Shortly, it is possible to read:

Code: Select all

udevadm: symbol lookup error: /usr/lib/systemd/libsystemd-shared-246.so: undefined symbol: crypt_activate_by_signed_key, version CRYPTSETUP_2.0
/init: line 96: [: -gt: unary operator expected
/usr/lib/systemd/systemd-udevd: symbol lookup error: /usr/lib/systemd/libsystemd_shared_246.so: undefined symbol: crypt_activate_by_signed_key, version  CRYPTSETUP_2.0
/init: line 157: [: _lt: unary operator expected
udevadm: symbol lookup error: /usr/lib/system_/l1bsystemd-shared-246.so: undefined symbol: crypt_activate_by_signed_key, version CRYPTSETUP_2.0
/lib/dracut-lib.sh: line 541: [: -ge: unary operator expected
udevadm: symbol lookup error: /usc/lib/systemd/libsystemd-libsystemd_shared_246.so: undefined symbol: crypt_activate_by_signed_key, version CRYPTSETUP_2.0

Then the display goes looping, and fills the screen with:

Code: Select all

/lib/dracut-lib.sh: line 531: [: -ge: unary operator expected
udevadm: symbol lookup error: /usc/lib/systemd/libsystemd-libsystemd_shared_246.so: undefined symbol: crypt_activate_by_signed_key, version CRYPTSETUP_2.0

I then went for a chroot, from a freshly installed mageia 8 on an spare partition.

Code: Select all

urpmi --auto-update

I ran more updates, without getting a clean reboot. The first command is invoked again, and ends correctly.

Code: Select all

su -c 'mgaapplet-upgrade-helper --new_distro_version = 8'

Unfortunately, the reboot does not get better.

Then came the time to update from a USB key dedicated to netinstall. The process completed successfully, but boot still shows the same errors.

What can I do now?
Attempting to temporarily uninstall systemd?

to be continued...

You could have mentioned that you crossposted this on the french forum and got many help there also...

Yes, thank you very much sturmvogel.

Yes, and seems it's already fixed.

Please don't forget to mark the thread as solved, by editing the subject of the first post and prefix it with [SOLVED], thanks in advance.

Be sure I won't forget to mark it as solved if I get in, or say if I ended in making a clean install.

What we have done on french forum until now is more like cleaning useless mga7 packages which were not updating in my "trying to rescue" process. We have spotlighted differencies between packaged files, and installed again some ones `urpmi --replacepkgs pkgsNamesList`. The pakages update looks finished.
But, the problem is still the same, and I do not see obvious link between crypt_activate_by_signed_key symbol and the remaining ideas to dig in.

My non bootable system is now mageia 8, hence I do not see how to run Mageia_7to8_update process again from net-install USB key.

PS : In french we say something like : "The best jokes are the shortest". What about : "The best puzzles are the ones with the most elegant solutions" ?

This is now fixed.

The problem was a broken init.
So the quick way maybe to chroot from another mageia8, and run dracut.
It may be useful to finish updates first.

After chroot in broken system :

Code: Select all

cd /boot
dracut -f initrd-5.10.52-desktop-1.mga8.img 5.10.52-desktop-1.mga8
