As far back as I remember this has been the case... I think it's an OS feature that the currently running process does not inherit the new group list from /etc/group. It's only when the process starts that the group list is read.
I'm not sure this is a bug, but it's really about the state of the process. So it's a kernel issue if at all. ** Package changed: gdm3 (Ubuntu) => linux (Ubuntu) -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1771308 Title: Adding the user to a new group doesn't take effect on logout and back in Status in linux package in Ubuntu: New Bug description: Steps to reproduce: Log in to a GNOME session Use adduser to add yourself to an existing group Log out and back in Open a terminal, run "groups" and notice that your user isn't in the new group.
