you dont run apt upgrade EVER since it doesnt upgrade dependencies and potentially breaks things.
only apt full-upgrade or apt dist-upgrade are permitted.

Have tried apt full-upgrade and apt dist-upgrade but the result still same:

Also "dpkg --configure -a" and "apt --fix-broken install" does not help

only apt full-upgrade or apt dist-upgrade are permitted.

any chance to update this proxmox 7?

Hi,

have you try this (in order) :

Code:

apt clean
apt update
apt -f install
dpkg --configure -a
apt full-upgrade

Best regards,

have you try this (in order) :
Code:
apt clean
apt update
apt -f install
dpkg --configure -a
apt full-upgrade

All above has been executed, to make sure I run them again here:

could you add modify the file /usr/share/initramfs-tools/hooks/btrfs so that the line with "set -e" says "set -ex" and re-run the upgrade command and post its full output?

There is no .../hooks/btrfs file

okay, what about "dpkg -l initramfs-tools" ?

it seems like you at some point had backports enabled and installed some packages from there, and there might now be a mismatch or a partial upgrade situation..

you can probably sort the concrete problem out by doing something like

Code:

touch /usr/share/initramfs-tools/hooks/btrfs
chmod +x /usr/share/initramfs-tools/hooks/btrfs

to put an empty executable file there.. but the question is what else is broken like that..

could you do "ls -lh /usr/share/initramfs-tools/hooks/" ??

you can probably sort the concrete problem out by doing something like
Code:
touch /usr/share/initramfs-tools/hooks/btrfs
chmod +x /usr/share/initramfs-tools/hooks/btrfs
to put an empty executable file there.. but the question is what else is broken like that..

Doing so for ../hooks/fsck and voila the apt update finally working, thanks!

Just run #apt upgrade on Proxmox 7, but error.

Code:

root@poweredge:~# pveversion
