I have Ubuntu 18.04 and python 3.7.
uname -a
Linux username-laptop 4.15.0-109-generic #110-Ubuntu SMP Tue Jun 23 02:39:32 UTC 2020 x86_64 x86_64 x86_64 GNU/Linux
When I run sudo apt-get update
I get this error :
E: The repository 'http://dl.bintray.com/aluxian/deb stable Release' does not have a Release file.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.

I tried this solution but I am also unable to open Software and updates.
