Comment 11 for bug 1855259

Paulo, please note:

a) Repairing a system using the steps in comment #9 doesn't address the underlying problem, and so it could potentially break again.

b) Sophos doesn't support newer kernels and Ubuntu 19.10 is explicitly not supported at present. While it mostly works, their released Talpa on-access scanning component does not successfully compile for Ubuntu 19.10, and so Sophos falls back to using fanotify for that functionality (if support for it is available in the kernel). So, it turns out that the root cause of this particular problem is either a bug in fanotify itself, or a bug in the way Sophos is using it. (I couldn't say which.) A patch for Sophos' Talpa component that will supposedly get it compiling and working on 19.10 is apparently available, but I haven't tried it myself: https://github.com/sophos/talpa/issues/17 More details can be found here: https://community.sophos.com/products/server-protection-integration/f/sophos-anti-virus-for-linux-basic/117256/sav-protect-service-breaks-system-updates-on-ubuntu
