I don't whether this is related, though. This is because /usr/libexec/nm-dhcp-helper exists in 1.44.2-3 and 1.44.2-4, but not in 1.44.2-1. I suspect that nm-dhcp-helper has been added because it is now needed. But it doesn't work due to the "Permission denied". I've attached more journalctl output, in case it is needed. -- Vincent Lefèvre <vinc...@vinc17.net> - Web: <https://www.vinc17.net/> 100% accessible validated (X)HTML - Blog: <https://www.vinc17.net/blog/> Work: CR INRIA - computer arithmetic / AriC project (LIP, ENS-Lyon)
