urpmi.update -a That will refresh your urpmi database from all the online sources you have defined. You should run this command before you attempt to install anything. Running the MandrakeUpdate GUI will run it automatically. As for bad signatures - A bad signature simply means that the signature the packager signed the package with does not match the signature key you have stored for that source, and so you cannot be confident you know who actually created the package. This could be because of a number of reasons. 1/ You do not have a signature key stored for that source. 2/ The packager was careless and either did not sign the package or signed it with the wrong signature. 3/ Someone has tampered with the server and inserted a malicious package on the server. 1/ and 2/ are by far the most likely reasons. So do not immediately assume the servers have been tampered with every time you see a bad signature message. (I can only recall one instance of a Linux software server being tampered with when the Openssh project's download site was tampered with a few years ago. It was discovered and fixed within 24 hours) Normally it is quite safe to accept the bad signature and continue with the install so long as you trust the source you have defined. (And if you do not trust your sources what are doing installing software on your computer from them?) If you do have bad or missing keys you can fix it. Open MandrakeControlCentre>Software>MediaManagement You will see a list of your sources. Click on 'Manage keys' and you will see which keys are associated with each source and you can see if a key is missing. To re-add a key click on 'Edit' in the media management menu and click on 'Save changes' The source will be refreshed and if the key is available it should be re-added automatically. For some sources such as Charles Edwards' site this procedure does not seem to work in which case you can add the key manually. wget http://www.eslrahc.com/10.1/CAE.asc && rpm --import CAE.asc Then go to MCC>Software>MediaManager and associate the newly imported key with Charles' source. derek -- www.jennings.homelinux.net http://twiki.mdklinuxfaq.org
