Bug Description


Sorry i have been having soo much problems with Linux lately (I'm a noob). But back to my problem...anytime when i try to install or uninstall anything it gives me this error message

"Only one software management tool is allowed to run at the same time.
Please close the other application e.g. 'Update manager', 'aptitude' or 'Synaptic' first."

I have tried restarting multiple times! I made sure that nothing else was running. Could you please tell me any programs that may be causing this and how to solve it?

Have you tried running top in a terminal? It should let you know what programs are running

I'm not a n00b. This happened also to me, and while I'm confortable with quite a bit of Linux administration I have used nothing but the Ubuntu happy-wrappers for many months. They typically work great. I'm on 6.06 still.

I strongly suspect there is a real bug underlying this; possibly triggered by e.g. doing multiple "download and install" cycles when prompted, but postponing one of the required reboots.

Regardless, running the synaptic packagage manager rather than just the update manager produced a more helpful error message, that dpkg had struggled and the correct commandline to proceed. To recover, (adding sudo) at the command line I ran:

sudo dpkg --configure -a

entering my password when prompted.

Note that I had killed the update-notifier previously during debugging of the problem. I have no idea if that was related; I doubt it but wanted to give full disclosure.

Please, can you tell me which packages has dpkg configured?
Also, did you try to install packages with apt-get?
