Issues when installing vanilla gnome on Ubuntu 21.10

Solution 1:

Ran into the same issue. There seems to be some naming changes that result in this problem. The mailing list did provide an answer:

I have a manual fix for this.

Edit "/var/lib/dpkg/info/vanilla-gnome-default-settings.postinst"

Change "gdm3-theme.gresource" to "gdm-theme.gresource"

Then "sudo apt install -f"

The vanilla gnome setup now works as expected.

I can confirm this worked for me!
