I had KDE installed on my computer a bit ago. Switched back to gnome in 18.04. Recently upgraded to 20.04 and realized the Kubuntu loading screen still shows on startup. Did some research and found info on plymouth themes.
Went to change it and was disappointed to find that
ubuntu-logo was not in my themes folder. Furthermore,
apt search plymouth-theme gives me a list with
plymouth-theme-ubuntu-logo/now 0.9.3-1ubuntu7.18.04.2 amd64 [residual-config]. When I run
sudo update-alternatives --config default.plymouth (found on an AskUbuntu answer from 2014), only kubuntu and bgrt are listed.
I tried to re-install the ubuntu-logo theme with
sudo apt install plymouth-theme-ubuntu-logo, but got:
Package plymouth-theme-ubuntu-logo is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'plymouth-theme-ubuntu-logo' has no installation candidate
How can I re-install the default ubuntu-logo plymouth theme?
