title: Kernel postinst issue on Linux Mint
|
|
|
|
The other day I got my Linux Mint system not booting anymore. I suspected this was due to my custom script I placed in `/etc/kernel/postinst.d/` that is needed to copy the latest kernel in my EFI partition after an APT update, to allow boot via efistub bypassing grub. Maybe an unattended upgrade of my kernel failed.
|
|
|
|
After manually fixing the EFI partition to boot again in the system, I tried manually to run `apt upgrade`, and saw that my postinst script threw an error due to not finding one of the files to copy from `/boot` to `/boot/efi`.
|
|
|
|
After a quick web search, I saw that files in `/etc/kernel/postinst.d` should be numbered as they get run in the proper order by run-parts. I did `ls` on the directory where I've put my script to be certain that it was the very last, and actually it wasn't.
|
|
|
|
```
|
|
$ ls
|
|
dkms
|
|
initramfs-tools
|
|
pm-utils
|
|
---> UpdateEfiBoot <--- My script
|
|
xx-update-initrd-links
|
|
zz-shim
|
|
zz-update-grub
|
|
```
|
|
|
|
This was ugly to fix since, as seen in this list, my distro's mantainers are geniuses and decided to get rid of numbers, and instead prefer to just use alphabetical ordered naming, falling back to ugly letter suffixes when that plan failed. I renamed my script from `UpdateEfiBoot` to `zzz-UpdateEfiBoot` and that fixed the issue.
