Ubuntu 9.04 errors 'Error failed to fork pty' running update manager and using terminal

Asked by jdfilburn on 2009-10-27

Update Manager checks for software updates, but upon clicking "Install":

'Error failed to fork pty'

And after launching terminal to try and get updates manually:

'There was an error creating the child process for this terminal'

Having trouble finding a a solution that I can get working on this pc. Yes, it's probably because my level of understanding of linux is low.

Any step-by-step assistance is appreciated.

I can't seem to get either method mentioned in the bug#338071 to work. The errors are persistent.

Perhaps I am not applying them correctly:

Method 1: edit fstab:
ALT+CTL+F2
[logon]
sudo -e /etc/fstab
----added line at bottom--- 'devpts /dev/pts rw,noexec,nosuid,gid=5,mode=620'
save/exit
sudo mount -a

result: both errors persist. and mode=620 produces a nice red 'Fail' upon startup

Method 2: move mountdevsubfs.sh:
ALT+CTL+F2
[logon]
sudo mv /etc/init.d/mountdevsubfs.sh.dpkg-dist /etc/init.d/mountdevsubfs.sh

result: both errors persist. no noticeable change confirmations

Problem solved, likely by Method 2 above, as I restored the fstab file to the pre-Method 1 state prior to commencing.

All I apparently needed to do after Method 2 was reboot the system. Terminal and Update Manager applications now function without errors.
