[Solved] grub-mkrescue: error: Decompressor is too big.

Hello.
I've been following the bare bones tutorial on the wiki, but when i execute the grub-mkrescue command, this error happens:

Code: Select all

grub-mkrescue: error: Decompressor is too big.

I've seen this error on the forum (I haven't understood it), but i'm using Ubuntu on WSL, not Cygwin.

Sounds like it could be this bug. Try updating your installed packages.

If you don't want to wait for all of your packages to update, try updating just GRUB.

Code: Select all

# apt update
# apt install grub-pc-bin

I updated all packages, but the same error happens.

Which version of Ubuntu on WSL are you using?

[ForgeLoxus]

20.04.1 LTS. I'm still using wsl 1 because i haven't updated to 2004 yet.

I installed that version of Ubuntu in WSL (not WSL2) but I can't reproduce the issue.

I've found the solution:
I uninstalled the grub I installed from source, then I did

Code: Select all

apt install grub-common
apt install grub-pc-bin

Then, grub-mkrescue worked.
