Error: Failed to Unshare remaining namespaces

Posted 1 Oct 2024 by [AF>Libristes] Kao Post: Well I've found out what's happening. I also have docker on that machine. Which is using, I assume, a custom version of runc that, for whatever reason, does not work with LHC apps. Is there a way to force LHC to NOT use the local runc? |

Posted 1 Oct 2024 by [AF>Libristes] Kao Post: I already had issues on the 28th : https://lhcathome.cern.ch/lhcathome/result.php?resultid=414588095 That's why I don't understand why it started to work and then to not work again. I will try what you are proposing tonight. In the event it does not work are you saying I should try to install runc 1.12? The only thing I did to runc was using apt update. So if Ubuntu's repo have bad versions... rip |

Posted 30 Sep 2024 by [AF>Libristes] Kao Post: Hi, I'm getting a "failed to unshare remaining namespaces" error on some native tasks but not all of them. Here is one that failed: https://lhcathome.cern.ch/lhcathome/result.php?resultid=414634007 Here is one that succeeded: https://lhcathome.cern.ch/lhcathome/result.php?resultid=414604581 I'm not sure to understand what's happening, and i've tried everything i had in mind for fixing this. Including the "kernel.unprivileged_userns_clone = 1" kernel setting. The machine is running ubuntu 24.04 Thanks for your help |
