Bug#1099884: mutter: Failed upgrade from gnome 47 to 48: crash at gdm3 startup: white screen

[Emmanuel Arrighi]

Hello,

I got the same situation when upgrading to 48~rc-2. I solved it by doing 
an `apt full-upgrade`. Some packages (for example mutter-common-bin) got 
updated only with the "full-upgrade".

I hope this helps.

Best regards,
