Hello, I have done a search about the problem I'm having, but didn't really find anything. If it's been discussed to death before, please just point me to the correct threads. Here goes: I have an Acer Aspire One (linpus) in which I have enabled the advanced mode. Everything was fine until about last night, when I decided that I wanted to install Skype. I downloaded the package from the Skype site (Fedora) and double clicked it. It prompted me for the root password (so far so good), I entered it, up popped the "Installing packages" box ....but it was completely blank, just a grey box with no text or buttons. I left it for about 20 minutes to see whether anything happened, then I killed it. After that I tried the Add/Remove option in System. It doesn't do anything at all, the window doesn't even appear. I started a terminal session, su'd to root and tried starting pirut. It just hangs. I can see the process running in the background, but nothing happens in the terminal window, not even error messages. I tried yum clean all, just in case. That has been running for the last 30 minutes again with no messages whatsoever, so I expect that's hang too, so I'm going to go and kill it. Any idea of what may have gone wrong and where I should look next? could it be a python issue? I have added software before successfully, so this is something that has happened recently. Thanks in advance, Fede
