I used to have two kernels installed (56 and 57). At some point kernel 56 was removed with a system update (in fact kernel 56 is not installed if I check in Manjaro Settings Manager, and it can no longer be installed). However, in the grub menu at startup kernel 56 is still shown. If I run
sudo update-grub I get the following:
Generating grub configuration file ...

It is not a big deal, but I’d like to remove this image of kernel 56. How can I do that?
sudo mhwd -r linux56
sudo pacman -Rns linux56
Thanks! Both the commands
pacman -Rns fail.
The first gives:
Error: invalid use of option: -r/--remove
The second (my translation, the original English might be different):
error: the following package was not found: linux56
Looks like the package was properly uninstalled…
Oops. I accidentally gave you
mhwd instead of
mhwd-kernel -r linux56
But yes. OK. Well … lets look in
/boot/ then …
find /boot/ -type f -name "*5.6*"
pacman -Qo any files you find … to see if they are owned by any package.
If not … you can
sudo rm any of those files.
sudo update-grub again.
Indeed, this command returns
find: ‘/boot/efi’: Permission denied
I guess the files
can be safely removed.
If they arent owned by any package and you dont have 5.6 … yeah … they should be disposable.
I guess you can rerun the command with sudo … or just manually take a look in your efi directory. There shouldnt be anything related there… but just because it couldnt technically check it.
Files removed, grub menu now looks correct. Thanks!
That was a random hiccup. Glad its sorted
