The solution presented there did not work, so I tried this instead:
sudo rm -R /var/lib/pacman/sync
That worked and I got my packages updated via the command line with pacman and yay. However, Pamac still shows updates for dbus-x11, game-devices-udev, snapd, v86d, xcursor-breeze and yay, all originating from AUR.
This is the output for yay:
:: Synchronizing package databases...
core is up to date
extra is up to date
community is up to date
multilib is up to date
:: Starting full system upgrade...
there is nothing to do
:: Searching databases for updates...
:: Searching AUR for updates...
-> kvantum-theme-matchama: local (20191118-1) is newer than AUR (r265.8525e05-2)
-> Missing AUR Packages: galculator-gtk2 libopenaptx
there is nothing to do
If I try to update with Pamac again, it will give the
error: GPGME error: No data
error again.
What should I do to stop this error from coming back?
As far as I see these are obsolete packages dropped from repository and put to the AUR.
Definitely not. All of these packages are also in the official repositories. None of them are orphans. Pamac seems to say that I have it from the official repositories as well as AUR. Very strange. These packages are either explicitly installed (e.g. snapd is installed by default on Manjaro) or a dependency for another package.
Yeah, sorry for the confusion, it wasn’t intended. Thanks to @maycne.sonahoz for correcting me.
However, was referring to galculator-gtk2 libopenaptx, respectively kvantum-theme-matchama which seems local but requested from AUR also.The first 2 are neither in repo nor in AUR, one is only as -git version.
