I have Ubuntu 19.10 and am trying to upgrade to 20.04.1. I have followed all kinds of tutorials, but in the end I am always facing the same problem. When I run
sudo do-release-upgrade
The log is:
Checking for a new Ubuntu release
Your Ubuntu release is not supported anymore.
For upgrade information, please visit:

If I run
sudo do-release-upgrade -d
The log is:
Checking for a new Ubuntu release
Upgrades to the development release are only
available from the latest supported release.
I also tried upgrading from Software Updater, and when I try to, the window just disappears. By the way, I have 1GB free memory, I don't know if this could be the problem.
P.S: The output of lsb_release -a:
No LSB modules are available.
