Error running apt update command on Azure Ubuntu VM

Question

I am facing an issue on my Azure Ubuntu VM with the apt update command failing. The error message displays "the repository does not have a release file". However, the azlux.fr repository is not in my apt repositories list.

Can someone help me fix this issue? Any suggestions or ideas would be appreciated.

Hello Shin Juyong

Welcome to Microsoft Q&A Platform, thanks for posting your query here.

It seems like you are trying to update your Ubuntu VM using the apt update command, but you are getting an error message saying that the repository does not have a release file. You also mentioned that the azlux.fr repository is not in your apt repositories list.

Based on the information you provided, it seems like the azlux.fr repository might have been added to your system at some point in the past, but has since been removed. However, the repository information might still be cached on your system, which is causing the error message you are seeing.

To fix this issue, you can try removing the cached repository information for the azlux.fr repository by running the following command:

sudo rm -rf /var/lib/apt/lists/*

This command will remove all cached repository information from your system, which should include any cached information for the azlux.fr repository. After running this command, you can try running the apt update command again to see if the issue has been resolved.

If you are still having issues, you can try checking your /etc/apt/sources.list file to see if the azlux.fr repository is listed there. If it is, you can try commenting out the line that references the azlux.fr repository and then running the apt update command again.

I hope this helps!
