After upgrading to udev 026-r1, that changed default_mode in /etc/udev/udev.conf from 0666 to 0660 I'm not able to use ssh from a normal user. === $ ssh gibo@fry ssh_askpass: exec(/usr/lib/misc/ssh-askpass): No such file or directory ssh_askpass: exec(/usr/lib/misc/ssh-askpass): No such file or directory ssh_askpass: exec(/usr/lib/misc/ssh-askpass): No such file or directory ssh_askpass: exec(/usr/lib/misc/ssh-askpass): No such file or directory Permission denied, please try again. ssh_askpass: exec(/usr/lib/misc/ssh-askpass): No such file or directory Permission denied, please try again. ssh_askpass: exec(/usr/lib/misc/ssh-askpass): No such file or directory Permission denied (publickey,password,keyboard-interactive). === This is due to the owner of /dev/tty, which is root:root:0600 I solved the problem adding this line tty:root:tty:0660 to my /etc/udev/permissions.d/50-udev.permissions and making my user a member of the tty group
