Screen Fails When Detaching Screen Session

[justingoldberg]

I am using chrome and windows 10 64.

Screen fails when typing Ctrl-A and then D, to detach the active screen session.

It fails on two different QNAP NAS, one with an ARM cpu and also another one with an AMD 64-bit cpu.

Here is what happens:

[] # screen -v
Screen version 4.00.03 (FAU) 23-Oct-06
[] # screen
[~] #

Screen version 4.00.03 (FAU) 23-Oct-06

                                                                      [Press Space or Return to end.]

I run sleep 60 & at this point.

Then I detach with ctrl-A then D.

I get this error:

[detached]reen
[] # un/utmp: No such file or directory
[] #

However the screen sessions are still running as shown below:

[] # screen -r
There are several suitable screens on:
4064.pts-1.QNAP (Attached)
3037.pts-1.QNAP (Detached)
28898.pts-1.QNAP (Detached)
26651.pts-1.QNAP (Detached)
26628.pts-1.QNAP (Detached)
6980.MYTRANSCODE (Detached)
Type "screen [-d] -r [pid.]tty.host" to resume one of them.
[] #

Everything seems to be working however, I am able to reattach to the detached screen sessions.

Yeah, I know, I need to learn tmux.
