  • sudo apt-get update
  • sudo yum clean metadata
  • sudo yum makecache

These commands will help update the repository list and clear the cache, which may fix the error.

Check Repository Files

If all the previous steps didn’t help, try checking the contents of the repository files in the /etc/yum.repos.d/ directory. There might be some errors there that are preventing the update.

Correct the errors in the repository files or delete them, and then repeat the steps to update the repositories.

Check Proxy Settings

Sometimes the problem may be related to proxy server settings. Make sure the proxy is configured correctly and is not blocking access to the repositories.

If a proxy is used, try temporarily disabling it and retrying the update.

Contact Support

If none of the above methods helped, seek help from specialists. Perhaps the problem lies in deeper operating system settings.

Don’t despair, errors happen, and there is a solution for each of them. The main thing is not to be left alone with the problem and seek help!
