so that Eclipse will query the update site you just entered for contents.Before proceeding, it's recommended that you UNCHECK the 'Contact all update sites during install to find required software' (it will still work if you don't do that, but it'll query all the update sites available, which is much slower than querying only the Py Dev update site, which should be all that's needed to install Py Dev).Available update sites for sts are listed here:

My anti-virus has an exception for my hole eclipse folder.

Now, select Py Dev for Eclipse to install Py Dev (and optionally the Py Dev Mylyn integration or the developer resources, which provide the Py Dev source code) and click Next.

Now, read the license agreement and if you accept, select the accept radio button and click Finish.

Removing from the "Available Software Sites" in Eclipse, and adding it again did the fix. After exporting and importing bookmarks, the problem did not get resolved. On further thoughts I found that my antivirus is not allowing eclipse to talk to internet. Sandeep Jindal I had a similar problem over the last couple months, but ignored it until I really needed Py Dev to work on my laptop today.

I tried the solutions above to no avail and then I found something odd: In (Window-Available Software) I noticed that the box for 'Py Dev Update Site' AND another one right below it with the location 'file:/updates' were both checked, causing a duplicate of most or all update URLs.

The best solution is to become root using su or by logging in as the root user from the start, if you have that ability (Ubuntu users don't, unless they fixed that defect).

The first thing to choose before the install is a folder where you have permissions to write (otherwise, remember to install Eclipse running as an Administrator and remember to run as an Administrator whenever any plugin needs to be updated).

The only issue, is that when I installed through the software center, the owner became root, and whenever I run it without root, I'm not able to update - I get the error message "Insufficient access privileges to apply this update." When I run it as root, all of my plugins disappear, because I guess I installed them as myself, not as root.

I tried to install the plugins as root, but the Install New Software choice would not work.

It never used to do this, everything was working find until last week (Sept 25th (ish) 2012) When I encountered a similar problem I add the following repository to my available update site. Both were present and checked in Install/Available Software Sites.
