Hi once more.
After recently updating my computer, I came back to find the screen frozen on the Ubuntu-MATE welcome screen. After restart it, I got an error message which said something like “Kernel Panic: Not syncing: VPS: Unable to mount root fs on unknown-block(0,0)” (I can also post a screenshot if anyone needs it). I have tried live booting the machine and checking the hard disk and files on it and everything seems to be fine. I tried loading an older kernel which seemed to work. However, the back of the welcome screen was black and I couldn’t get an internet connection (without some command prompt work).
Just before updating, I added the artful repository which may have introduced newer or unstable software to my system. I did this to install a newer version of a program but it seems that it has done the same for everything. Prior to adding the new repository ppa, I only had xenial ppas in the sources.list.
So my question is: What can I do to get my system back to normal? Do I need to rollback the update? If so, how?
Thanks in advance for any help with my problem.
