How to upgrade Ubuntu Studio 20.04 LTS to Xfce 4.16?

Solution 1:

You have to add special PPA from “Xubuntu Developers” team named Xubuntu QA Staging and install packages from it by executing commands below:

sudo add-apt-repository ppa:xubuntu-dev/staging
sudo apt-get update
sudo apt-get dist-upgrade

Note: to revert the changes use ppa-purge by sudo apt-get install ppa-purge; sudo ppa-purge ppa:xubuntu-dev/staging .

Solution 2:

If you do this, prepare for possible instability:

• Random logout bug (startx shutdown) when removing indicator applet (normally changing various settings to your taste), or randomly during the next session. after that, without debugging, that user graphical UI session is done indefinitely.

• On unlock screen it is quite possible you will not be able to enter your unlock password, as the keyboard input and focus will be nonexisting (X input problem?) (only solution for me was to hard power off)

initial bug report is up at XFCE gitlab under session

Just some thoughts on the problems experienced some time after upgrading to Xfce 4.16
