Directory '/var/run/screen' must have mode 777.

[amace]

I have a new install of 4.4 that has subject problem with screen. I can fix the problem by chmod 777 but I don't understand why the problem comes back after each reboot. This problem started after I backed up the OS (fresh install) and restored it on md/raid. Other installations I've done, that have not been backed up and restored, work fine with the standard permissions:

drwxrwxr-x 2 root utmp 40 Jun 12 21:33 /var/run/screen/

Not finding anything definitive on google search. Only solution I've found is chmod 777 /var/run/screen ... Has anyone else seen this error and/or have a fixx?

Hi,

I have a new install of 4.4 that has subject problem with screen. I can fix the problem by chmod 777 but I don't understand why the problem comes back after each reboot.

Force reinstall screen to bring it in a good state again:

sudo apt-get --reinstall install screen

Also I suggest that you give "tmux" a look, it is a modern alternative to screen with a few more features, just as a side note.

Thanks. That is so obvious I wish I'd thought of it! So far so good!
