Yesterday, I tried to install free cad from synaptic but when the downloading pop up comes, my whole system freezes. When this happens I have to forcefully shut down my system (by holding the power button) and restart. This is a new install of zorin os 15.3 and the recovery mode is not working. I just wanted to check if my os or perhaps the file system is corrupt? Is there any way to fix the recovery mode?
Any help will be appreciated
