Hi, now I have (man ... I'm stupid) installed Java and I had no idea how I can uninstall it so I just deleted the folder with all Java files (on Windows that doesn't do the job because of registry file -- seems to be the same on Linux ;-)). Now I wanted to reinstall it and RPM is saying that it is already intalled ;-/ If I try to remove it with rpm -U *mypackage* it tells me that it is not installed ;-) What should I do now to deinstall it and install it again? Kind regards, delirium On Thu, 2004-12-16 at 09:30 -0500, Temlakos wrote: > On Thu, 2004-12-16 at 14:59 +0100, delir!um wrote: > > Hi everybody, > > > > I would like to know what RPM is?
