Failing to install IntelliJ from the Software Center, I realized my login is wrong in the /etc/apt/auth.conf entry that the install process generates.

In this file, I see my original OpenID, that's the one which got automatically generated when signing up on Launchpad. It contains my last name so I changed it.

I purged conf and binaries for Ubuntu One, reinstalled, deleted all listed "Devices" from app, all "Applications" from Launchpad. Deleted ~/.cache/software-center/, reboot, but still:

• When installing IntelliJ, the auth.conf file receives my original OpenID, not the modified one
• Problem is that the commercial subscription, for IntelliJ private PPA, uses my modified OpenID, so authentication attempt fails. I can't remove nor modify this subscription, even by changing back my OpenID into Launchpad.

Any idea to solve this?
