Missing AUR Packages, Orphaned And Newer Than The Available Package

@Thanks

How is it possible that the pygtk package is newer than the package available on AUR?

The missing AUR packages worry me because I never installed them manually, I don’t know any except galculator-gtk2 which is the default calculator preinstalled on Manjaro xfce. So, is it normal that galculator-gtk2 seems to come from AUR?

Finally, the three packages to be updated, I never installed them manually, don’t know where they come from, nor what they are used for, etc., that worries me. Is it possible that these packages came from a core, extra, community, etc. repository and that since the system update, now they come from the AUR repository?

As @anon89812132 pointed out, most packages come upstream from Arch, and they regularly remove packages from their repositories. Those packages then end up in AUR.

Again, for the missing AUR packages, how do I know if I can safely uninstall them and if they are no longer needed?

Packages in the repositories (usually) cannot depend on AUR packages. The only case you might want to keep them is if you use an application from AUR with those packages as dependencies.

Then, the libgee06 package is orphaned, how do I know if this is normal and if I can uninstall it if it is no longer needed?

In most cases, orphaned packages are not required by any other package, and thus can be removed.
