byobu

screen works; byobu doesn't?

Asked by Ghoti

On Ubuntu Karmic Server, when I SSH in and attempt to use Byobu, I get the following error:

ghoti@fortress:~$ byobu
Exit the current screen session to run byobu

I get the error with any mix of command-line paramaters I have tried.

However:

ghoti@fortress:~$ screen -ls
No Sockets found in /var/run/screen/S-ghoti.

Also, screen runs normally, without complaint.

Any ideas what could cause this or, more importantly, how to fix it?

When you try to run byobu, are you sure that you're not already in a
screen session?

Also, what's the value of echo $TERM?

There are no byobu or screen sessions running on the machine in question (that I am SSHing into and trying to run byobu on), but I am running byobu locally- does byobu not support nested screens?

ghoti@fortress:~$ echo $TERM
screen-bce

Indeed; when I connect using a non-byobu terminal, I can run byobu on the remote box. Is not allowing nested-byobu sessions the intended behavior?

In Karmic, it does not.

But it does now!

In the version you're running, that's true. However, it has since been fixed.

Go to http://launchpad.net/byobu and add the latest PPA if you want
this fixed. Otherwise, wait for Lucid.
