Just to compare with my system, what are the results of these commands? pkaction --action-id org.freedesktop.packagekit.package-install --verbose
and pkaction --action-id org.freedesktop.packagekit.package-remove --verbose
And, after you have started gnome-software and tried to remove/install a package pkcheck --list-temp
In addition, could you paste the content of /etc/polkit-1/rules.d directory? sudo find /usr/share/polkit-1/rules.d -type f
or simply sudo ls -la /usr/share/polkit-1/rules.d
Sorry @luca247 if I iterate around many requests, but it is not simple to troubleshoot an issue like this. Also because it never happened to me. I’m only figuring out if something could help us to identify the issue.
What is the result of this command?
pkcheck -p `pidof gnome-software` -a org.freedesktop.packagekit.package-remove -u
On my system, the window asking for the password pop up.
In addition, I’ve seen that GNOME Web doesn’t save passwords if the login keystore doesn’t exist. And again, I’m pretty confident that Vivaldi uses its own keystore (like Firefox does). So I suspect that these other issues are unrelated. But who knows, I’m a simple user like you.
firts of all, looking at your journalctl output, it is safe to remove /etc/rc.d/init.d/livesys-late (saves a log message - see entry ‘992’)
But that’s not really important now - i see a lot of gnome-shell errors, mayby reinstalling gnome-shell should kick something in the right direction?
edit: looking at your log, i remember why i disabled audit on my system: it is a log spammer. For a more readable log you could add audit=0 at the kernel command line in grub before booting. Reading your log there is a lot going on on your system, maybe try to disable some unwanted services with systemctl will make it better. Certainly remove the livesys-late, i saw it wants to start (through systemd) app-glib-liveinst\x2dsetup and fails.
But that log is hard to read, Otherwise try something like sudo journalctl -b | grep systemd to just get the systemd records and | grep gnome for output gnome related
