Hi,
i updated my system yesterday and after a reboot grub does not prompt me for a passphrase for my luks encrypted disk any more.
I was able to boot into a rescue system and could decrypt the disk there. So my data is safe at least. But i would like to repair the system instead of having to reinstall everything.
As far as i understand it, the passphrase prompt should be initiated by the initramfs and not by grub, right?
Regenerating the initramfs within the chroot gives me this output (can i ignore the shared library error?):

No, you cannot ignore the shared library error. One of the critical libraries on your system is corrupt, you need to reinstall it.

I reinstalled pcre and got some errors (see below)
mkinitcpio -p linux looks exactly the same afterwards as in my first post.

Because you reinstalled the wrong package. https://wiki.archlinux.org/title/Pacman … _databases
Why is Community still in the list? It's been gone for close to a year. https://wiki.archlinux.org/title/Pacman … nd_Pacsave

Reinstalling core/pcre2 repaired the libraries and mkinitcpio -p linux created a working initramfs.
System is booting correctly again.
Thanks, marking this as solved.
