Before running screen with sudo (so after a fresh reboot, when the error occurs), can you please post the output of ls -l /var | grep run and ls -l /usr/bin/screen
The first command should show the permissions of the folder /var/run as 755 (drwxr-xr-x) and owned by root:root The last command should show screen to have permissions 755 with sgid (rwxr-sr-x) and owned by root:utmp If the last command doesn't show something very similar to -rwxr-sr-x 1 root utmp 308228 2007-10-23 12:02 /usr/bin/screen Then run sudo chown root:utmp /usr/bin/screen sudo chmod 755 /usr/bin/screen sudo chmod g+s /usr/bin/screen Since this bug didn't have a package associated with it, I am filing it under "screen", though I expect this is a configuration problem and not a bug. Thanks in advance for the information requested. Let me know if the problem is solved. ** Changed in: screen (Ubuntu) Sourcepackagename: None => screen Status: New => Incomplete -- Screen must be started with sudo on first use https://bugs.launchpad.net/bugs/312259 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
