[07:20] <dennis81> I found the issue, it was grub-customizer:
[07:20] <dennis81> https://bugs.launchpad.net/grub-customizer/+bug/1992200
[07:20] -ubottu:#ubuntu-next- Launchpad bug 1992200 in Grub Customizer "version_find_latest has been removed from GRUB but grub-customizer still relies on it" [Undecided, New]
[07:20] <dennis81> so nothing to do with ubuntu 23.10
[10:36] <guiverc> well done for solving/finding issue dennis81
