[SOLVED] libvlc dependency conflict when attempting system upgrade

I have not used my computer outside of basic email or emulator gaming for a while, so I went a few months without a system upgrade. I went to upgrade and cannot get past a dependency conflict.

looking for conflicting packages...
:: libvlc-3.0.21-27 and libvlc-luajit-3.0.21-16 are in conflict. Remove libvlc-luajit? [y/N] n
error: unresolvable package conflicts detected
error: failed to prepare transaction (conflicting dependencies)
:: libvlc-3.0.21-27 and libvlc-luajit-3.0.21-16 are in conflict

If I try to remove libvlc-luajit, pacman won't let me or else it will break KDE. I don't have libvlc installed at all. I ended up running "pacman -Syu --debug" piped into a file and think I found the issue:

It seems that it's trying to pull in libvlc because libvlc-luajit does not provide everything vlc-plugins-base needs to run. I also saw that there was a reorganization of vlc dependencies in the aur, which may be part of why this is happening. It's looking to me like I should force remove libvlc-luajit and then install libvlc to replace it, but I'm new enough at this that I'm nervous to do it without another set of eyes. I was thinking the appropriate thing to do would be "sudo pacman -Rsc libvlc-luajit" then "sudo pacman -Syu" after. (I also know about the linux-firmware manual intervention I'll need to do along with this, but I wanted to focus the post on this issue)

Re: [SOLVED] libvlc dependency conflict when attempting system upgrade

So why did you answer 'n' when pacman asked you?

Re: [SOLVED] libvlc dependency conflict when attempting system upgrade

I went back and forth with this enough times to know that yes would also fail. I can give you the yes version of the output as well.

:: removing libvlc-luajit breaks dependency 'libvlc-luajit' required by vlc-luajit

Re: [SOLVED] libvlc dependency conflict when attempting system upgrade

OK, so the problem is vlc-luajit. Why are you using that instead of just vlc?

I don't remember why that was installed over vlc. If I try to remove it now I get this:

Don't remove it, just replace it with vlc by installing vlc at the same time as the update, ie -Syu vlc
