A bit of a backstory... I'm relatively new to using Ubuntu (maybe 2 years?).
I had always dualbooted before but recently I ditched Windows for Linux and installed Ubuntu 19.10 Eoan Ermie on my laptop. (I wanted to install Ubuntu 20.04 but the setup GUI never loaded and stayed black). I then updated Ubuntu 19.10 and used it for like a week before wanting to upgrade.
I ran all the commands to upgrade my current system then used
do-release-upgrade to upgrade via the Terminal. It went smoothly until the end where it asked me to restart.
y and pressed ENTER.
I knew something would go wrong when i started getting
failed to write reg messages, then it wouldn't restart. It just showed the Ubuntu logo and did not turn off, nor restart.
Would it help if I mention that my Ubuntu 19.10 was encrypted?
I force shutdown and turned on my PC. It booted and asked me for my password that will un-encrypt the drive.
I entered it in and it said it was successful, then I saw a black screen with a unmoveable mouse cursor.
I waited for like 30 minutes before shutting my laptop down and booting off Ubuntu 19.10 Live Usb. It said it could not detect any Operating Systems so the OS would have quite possibly been corrupted after the upgrade. I just reinstalled 19.10 and had just finished reinstalling all my applications.
This had happened to me before once and I left it and decided to try it again now. I searched the internet for a solution but never found one. Am I doing something wrong? If so, what can I do to do it the correct way?
Note: I cannot install it via a live boot method like a live usb because, even after installing the image multiple times from the Ubuntu website, the setup GUI never loads and stays black.
If you have a solution, it would be helpful to keep all my files and packages whilst upgrading.
I'm sorry if I am asking too much, and I hope you can help! :)
