[Bug 1730266] Re: package memtest86+ 4.20-1.1ubuntu8 failed to install/upgrade: unable to make backup link of './boot/memtest86+_multiboot.bin' before installing new version: Operation not permitted

[Fantu]

hi, I saw some different cases where upgrade or dist-upgrade fails for issue/unexpected cases on memtest86+ postinst.
One should be solved in 5.01-4 and 2 was solved in ubuntu patches now merged in recent debian versions (5.31b+dfsg-1 and 5.31b+dfsg-4) and are now all in Jammy version (5.31b+dfsg-4).
I did some upgrade tests with latest version on both debian and ubuntu without issues, but I'm not sure that there will be anymore in any case, especially some rare/particular ones.

Is there someone that already do upgrade to latest version (5.31b+dfsg-4) or dist-upgrade that include upgrade to that version in the process that can tell me is had issues please?
Is there someone that did or will do same upgrade with root on lvm (with/without snapshot) ad other more rare cases that can tell me if upgrade/dist-upgrade was ok please? (in that cases can tell me also if ok and not only failed)

Thanks for any reply and sorry for my bad english
