I'm getting "Dependency resolution failed" and "Missing package" errors when trying to install software on my Lubuntu 20.04 system. This happens both when I try to install .deb files directly and when using Discover software center.
I'm using the out-of-the-box Lubuntu 20.04 and haven't updated it because I don't want to slow down my system. However, if updating would fix this problem, I'm willing to do it.
Note: I've already tried sudo apt update but it didn't resolve the error.
