Reading package lists...
E: The repository 'https://ppa.launchpadcontent.net/george-edison55/nitroshare/ubuntu jammy Release' does not have a Release file.

The nitroshare PPA software doesn't (currently) have a release compatible with the version of Linux Lite being used which is jammy based.
This conflict is preventing the update process from running.

To allow the update to run, the incompatible PPA has to be removed from the update list.
It is possible to do this in isolation, but as described at

https://www.linuxliteos.com/manual/software.html#pparem

if any unsupported PPA software is installed, that software should really be removed from the system before the PPA is removed from the software list.

If using PPA software, it is important that the PPA has a release that is compatible with the OS in use.
See the manual at this link for advice on selecting and installing PPAs

https://www.linuxliteos.com/manual/software.html#ppa

It's in Lite Software.
