Error when trying to remove duplicate grub entries

I received this error when using ujust regenerate-grub or ujust configure-grub:

Generating grub configuration file ...
mount: /var/lib/os-prober/mount: fsconfig system call failed: No such  file or directory.
dmesg(1) may have more information after failed mount system call.

done

Any ways to solve this issue?

cannot replicate, will need sudo dmesg | fpaste after you get the error since all you provided us is "there was an error, run dmesg to see more info"

In case if it's a partition related issue due to dualbooting, here's my partition setup, I also have an SD Card inserted on my Legion Go

Parmethyst•2w ago

in case anyone stumbled upon this, disregard the unrelated image at the bottom

HikariKnight•2w ago

try

sudo touch /boot/grub2/.grub2-blscfg-supported
ujust regenerate-grub

sudo touch /boot/grub2/.grub2-blscfg-supported
ujust regenerate-grub

instead the grub2-switch-to-blscfg command we are using is having some trouble the os-prober error however i think you can ignore also /boot is always mounted

Ok, will try, thanks! Confirmed that grub regenerated properly 👍
