Unable to open pty: No such file or directory
This error is a rare, but annoyingly found in some OpenVZ OS Templates. The resolution is to reboot your VPS through Wyvern until you are able to successfully login (may take multiple times) and then add the following code to the last lines of your /etc/rc.local file:
/sbin/MAKEDEV tty
/sbin/MAKEDEV pty
It is best to make sure that MAKEDEV is installed on your VPS prior to adding this code or it will do nothing. If you are unable to login to your VPS after multiple reboots, please open a ticket and we can assist you with this error.
