When running from a console with no DISPLAY variable, /usr/bin/up2date exits silently without any warnings/messages etc. This might not be
an up2date bug but perhaps with consolehelper.
When /usr/sbin/up2date is invoked directly it functions correctly.
When a DISPLAY value is set /usr/bin/up2date functions correctly
I can confirm this bug. Glad I found it in bugzilla, because it was driving me nuts.
Installed a fresh 6.2 system without X, had to jump through hoops to manually install
the dependencies for up2date, and then it wouldn't launch. When I tried
'/usr/sbin/up2date' though, it worked fine.
Once I ran all of the available 6.2 updates, I was able to run it as 'up2date'.
fixed in errata being released shortly.
