Thanks for the question.

I think you have better odds getting an answer if you provide more information.

Do you use Gnome or KDE as desktop (if KDE, KDE3 or KDE4?)?

Do you have any particular error message? What exactly happens?

Thanks

I am using gnome, there are no error messages. When I start root terminal, the panel shows "starting root terminal" also "starting administrative application", after a short time they are gone and no program has started. The timer is active while they are on the panel. This began after an upgrade to 8.04 from 7.10 on a Presario 1500 laptop. Update manager and linksys wireless card also broken. Thanks for any help you can offer.

I had the same problem after upgrading from 7.10 to 8.04 but after few patches it started working fine. Yesterday the problem show up again after the recent kernel upgrade. I have no error message, just the "starting administrative application" icon on the desktop bar that after maybe 10 sec disappear. apt-get from terminal works fine as well as sudo.
Thanks for your help

I solved the problem (I just followed the instruction to solve a problem in gksu/sudo, see question 34354 in launchpad) editing the etc/hosts file: I edited the second line (the one starting with 127.0.0.1 to look like 217.0.0.1 plus the name of my pc).I then saved to file, close and reboot and everything worked fine.
hope this help

Sorry I mistyped: it has to be 127.0.0.1 plus the computerhostname and not I repeat NOT as I wrongly typed "217.0.0.1 plus the name of my pc"). Sorry for that error

The Question he is referring to is 34350, "Problems with gksu & gksudo".

Just FYI.

Since gksudo will probably fail to open, you will have to use nano to edit the file.

"sudo nano /etc/hosts"

If "unable to resolve host {name of computer}" comes up in terminal mode, I would use that name as the 127.0.0.1 "computerhostname"

Gksudo and administrative applications both function properly now on my system.
