Not able to update Ubuntu 18.04 [duplicate]

  • 772

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.
N: See apt-secure(8) manpage for repository creation and user configuration details.

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

    I could finally solve the problem myself. Before that, I did sudo update-alternatives --config python3 and switched to python 3.6 python version change After that, I followed the answer of the same post (which I couldn't earlier because Software and updates wouldn't open) and unticked https://dl.bintray.com/aluxian/deb. Then the sudo apt-get update problem was solved !!!

  2. Probably find the repository is not on apt-get anymore. Use sudo apt update, it will then tell what packages need to be upgraded. Just upgrade them all by typing in sudo apt upgrade in your terminal. Update snap as well. Ubuntu relies on snap more so than apt-get and apt. Bit of a grey area in open-source software.
