REpository upgrade?

[ohjrson]

Yes. I *think* you have a 6.4 system which cannot update/upgrade properly because of the TeamViewer problem.
In turn this prevents the option to do in-series to 6.6.

The references to Teamviewer development and preview repositories are unexpected.
How did you install Teamviewer ? A- through the updates....

So How do I go about resolving this?----K so I thought I would just remove Team viewer using the install/remove software tool. ----- this is what happened.
