While upgrading my system from 19.04 to 19.10, there was power failure. Due to partial upgrade,my system after login shows me black screen for a while and then shows white screen with text on it-
"Oh no! Something has gone wrong. A problem has occured and the system can't recover. Please logout and try again."
I tried every possible thing available on Ask Ubuntu and Stack Overflow like upgrade, update, reconfigure lightdm etc. Nothing seems to work for me. Can someone help me with this ASAP?
I don't have backup of my data. So it would be great if you help me get my data back.
Thanks in advance:)

I had the exact same issue and fixed it by following below steps:
Trigger CLI from the error screen using Ctrl+Alt+F3 and Login. Then execute the command for release upgrade:
If there was issue with new release download, this should solve it, else it will print out:
No new release found.
If so, continue by updating the package lists and upgrading it.
If there was a issue here, the system will ask you to execute the command suggested by Schwab Eugen.
The system will finish unpacking and installing the missing resources. After that just reboot the machine and it should will work.
