Description
Describe the bug
On some jobs (apparently in a non-deterministic way) commands such as apt-get install fail with the following error:

For an example of such failure, check https://github.com/robotology/idyntree/pull/668/checks?check_run_id=560084383 . I would not be too surprised about CI jobs failing for networks problems, but this specific issue seems to be extremely frequent. I did not collect precise data on how much frequently this happens, but my impression that it happens in the order of magnitude of 1 out of 10 builds.
This issue is already being discussed on GitHub Community Forum at https://github.community/t5/GitHub-Actions/Install-dependencies-in-Ubuntu-flakes-several-times-a-wekk/td-p/51785 , but the GitHub support suggested me to open an issue here as well.
