I am fair new to ubuntu but I enjoyed the experience using version 20.04 LTS. I got a prompt to upgrade to the latest version and I've been trying to upgrade to version 22.
After download, I clicked the restart system buttom and since then I am unable to access the login page.
I am stuck in a black and white screen and the keyboard is not responsive.
Output:
[FAILED] Failed to start User Login Management.
[FAILED] Failed to start Switcheroo Control Proxy Service.
[FAILED] Failed to start Bluetooth Service.
[FAILED] Failed to start Network manager.
Please advise on how I can move forward, or how can I roll back to the previous version without losing data.
