Thank you Evan. I still don't understand what a "lock" is. But your hint to kill a process and your mention of the System Monitor got me to run the System Monitor. The most CPU was used by a process called "dropbox". I selected to end that process, was asked for my password, and thus succeeded in ending (killing?) that process.
My initial experience of attempting to install Dropbox was identical to that of the bug description at the top of this bug report. So I repeated the first of Patrick's 3 steps. I expected to see evidence of Dropbox starting another download. But Kubuntu 12.04's Konsole showed no evidence of anything other than that my command had been accepted (by presenting me with a prompt, after I entered my password). I then looked at my Muon Software Center window in which the progress window (for the installation of Dropbox), which previously showed it was stuck at 99%, was now replace by the message: "Dropbox File Sychronizer was successfully installed". That message also contained a Start button. I clicked that Start button and nothing happened that I did see. The task bar did not contain a Dropbox icon. I searched for a progam called Dropbox in the Kickoff Application Launcher and found nothing. I have a dual-boot setup on my ThinkPad G41 (2 GB RAM) with Windows XP and, in its own partition, a fresh (bare metal) install of Kubuntu 12.04. XP is hosting a VMware Player with guest Kubuntu 10.10. I attempted to install Dropbox on Kubuntu 12.04 to which I had copied my home folder of Kubuntu 10.10. That folder contained a Dropbox folder and a .Dropbox folder. I now wondered if I would have had better luck if I would have tried to get rid of those 2 folders prior to my attempt to install Dropbox. But I have not been successful in finding online help to tell me if it is safe to delete those folders. Now I'm hoping our bug report will solve our problem. In any case I thank you both Patrick and Evan for your help. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1016559 Title: nautilus-dropbox installation hangs while downloading To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/nautilus-dropbox/+bug/1016559/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
