It looks like your software may be past end of support.  Can you confirm the Linux Lite version please ?

The cybermax-dexter PPA software doesn't (currently) have a release compatible with the version of Linux Lite being used which is xenial 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.freecinema2022.gq/manual/software.html#pparem

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