@heynnema Sorry I didn't mean to. All I did was to update the firmware of my router and adjust my proxy configurations (which, as a matter of fact, doesn't need a proxy), change the content of sources.list and relative files, get back to the "main server" in the software updates app, and check to include all multiverse, restricted, ecc repositories. Then "sudo apt update --fix-missing && sudo apt upgrade". Now I have installed cpufreq instead of thermald to see if it works better
