LUbuntu announced the official backports PPA few months ago, to provide the latest LXQt desktop stack.

For those who are using this unofficial PPA for the latest LXQt packages, LUbuntu team recommends to remove it first.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run command to install the ppa-purge tool:

sudo apt install ppa-purge

Type user password (no asterisk feedback) for sudo prompt and hit Enter to continue.

Next, use the tool to purge unofficial PPA which also downgrade all installed packages:

sudo ppa-purge ppa:severusseptimius/lxqt

2. Add LUbuntu backports PPA

Then, run the command below in terminal to add the official PPA instead:

sudo add-apt-repository ppa:lubuntu-dev/backports

3. Update LXQt Desktop:

Finally, use the command below to update LXQt to v1.1.0:

sudo apt full-upgrade

NOTE: apt full-upgrade is required rather than apt upgrade, or some core libraries will be kept back.

For non-LUbuntu but Ubuntu 22.04 based systems, use the command below to install LXQt 1.1.0:

sudo apt install lubuntu-desktop
