@meiALICE : This is another failure unrelated to your code, as always, we alert in cases like this @vkucera

Hi @abilandz , there is no need to alert me in these cases. The "Git fetch failed" failures are caused by problems with a third-party repository which is not under our control and the tests recover automatically when the repository becomes available again, as explained in the error message.

@vkucera : Thanks for your feedback - I wanted to explicitly get your confirmation that the tests will recover automatically. But please nevertheless keep an eye on this PR, as still nothing has happened. Thanks!
