While it's not a fix coming from upstream, you can edit /etc/crypttab and turn this:
``` dm_crypt-0 PARTUUID=decafbad-1234-abcd-5678-aaaabbbb1234 /dev/urandom swap,initramfs ``` into this: ``` dm_crypt-0 PARTUUID=decafbad-1234-abcd-5678-aaaabbbb1234 /dev/urandom swap,initramfs,cipher=aes-xts-plain64:sha256,size=512,plain ``` (based on, amongst other posts, this: https://github.com/Sithuk/ubuntu- server- zfsbootmenu/blob/main/ubuntu_server_encrypted_root_zfs.sh#L1611C47-L1611C77) Then run `sudo update-initramfs -u` -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2060947 Title: Warnings produced in apt upgrade processing triggers for initramfs- tools To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cryptsetup/+bug/2060947/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
