How to Upgrade to LXQt 1.4.0 in LUbuntu 22.04
LUbuntu Team has made the new release package into this official Ubuntu PPA for current 22.04 LTS.

First, press Ctrl+Alt+T on keyboard to open terminal. When it opens, run the command below to add the official PPA:
sudo add-apt-repository ppa:lubuntu-dev/backports
Type user password (no asterisk feedback) when it asks and hit Enter to continue.
2. Update LXQt Desktop:
While adding the PPA, it should automatically refresh system package cache. So, your can then run the command below to update LXQt to v1.4.0:
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, user can use the command below to install LXQt 1.4.0:
sudo apt install lubuntu-desktop
In case you want to restore your system later, it’s better to written down what packages it’s going to install via terminal output.
When done, restart your computer and launch “About LXQt” dialog to verify.
