every time I tried to update anything I keep getting this error (I am new please help me)
error: While opening repository /sysroot/home/acer/.local/share/flatpak/repo: Invalid UTF-8
What do you see if you run this command in the terminal:
hexdump -C ~/.local/share/flatpak/repo/config
After running that command and sharing the output here, you could try running this command. Update: this is because the error message was related to this repository being corrupt. Do not run these commands in general.
mv ~/.local/share/flatpak ~/.local/share/flatpak.old
then logging out and in again. Some of your apps might disappear but updates should start working again.
Did updates start working again after you logged out and in again?
Thank you a lot! it worked.
