Fix RasperryPi apt install error: overwrite xxx but also in yyy

,

Try to run apt -f install on my Rasperry Pi 4 (Raspbian OS), but get following error:

1

Preparing to unpack .../gnome-software_3.30.6-5_armhf.deb ...
Unpacking gnome-software (3.30.6-5) ...
dpkg: error processing archive /var/cache/apt/archives/gnome-software_3.30.6-5_armhf.deb (--unpack):
 trying to overwrite '/usr/share/dbus-1/services/org.freedesktop.PackageKit.service', which is also in package pi-package-session 0.5
Errors were encountered while processing:
 /var/cache/apt/archives/gnome-software_3.30.6-5_armhf.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

The problem looks like it tries to overwrite some file but that file is being used by a package pi-package-session.

The solution is, remove that package first:

1
2
$ sudo dpkg -r pi-package
$ sudo dpkg -r pi-package-session

Now try apt -f install again, it should work now.
