Cache file could not be renamed error


I installed a fresh copy of Eclipse. I opened its Update Software section to install some software. The Mars section took forever to load and in the end threw this error:

Unable to read repository at
An error occurred while downloading
The cache file /home/joe/eclipse/p2/org.eclipse.equinox.p2.repository/cache/downloading/467561694 could not be renamed to /home/joe/eclipse_/p2/org.eclipse.equinox.p2.repository/cache/467561694.


This error persisted no matter if I restarted Eclipse. In the end, I just deleted the p2/org.eclipse.equinox.p2.repository/cache directory. The software list uploaded fine after that.

Tried with: Eclipse 4.5 and Ubuntu 14.04
