Pamac issues, can't update

[Kip]

So whenever I try to Refresh Databases in Pamac, I’m getting “Failed to prepare transaction” and “invalid or corrupted database”.

I have tried changing mirrors and updating mirrors, no help.

I’m a bit of a novice with Linux in general so not sure where to go from here. A quick search led me to some commands that gave me this output (I redacted most of the key itself, no idea if that’s important or not):

[paul@PC ~]$ sudo pacman -Syu
[sudo] password for paul:

Any idea what I can try to fix this? This is totally stopping me from running updates.

As mentioned above, the offending issue is that you have DEB_Arch_Extra repo added in your pacman.conf. Remove that repo and try again.

That repo is not a Manjaro repo.

My thanks to both of you. Feel slightly silly that I didn’t try to find out what exactly DEB_Arch_Extra was but oh well. Turns out, Mega Sync from AUR is the culprit. All I did was uninstall that and as if by magic, updates starting working again flawlessly. It’s strange because I’ve had Mega Sync installed pretty much since I set up Manjaro and only recently encountered the problem of not being able to update. Guess I’ll stick to using Mega via browser for now.
