thank you for any help,

Did you install Zesty (17.04)?

Moved to the Development Discussion / 17.04 Zesty

Did you install Zesty (17.04)?

well, I uprgraded Ubuntu but had some problems while upgrading and now I am with Zesty...I wanted to get Yakkety :grin:

iirc you can’t add ppa’s on a development version of ubuntu, like 17.04.

You can add PPAs, but there is a chance they do not have packages for that development release, so no packages can be found for that release.

A workaround is to temporarially point that source to a different release, e.g. yakkety or xenial.

Just remember that if you point lets say yakkety to xenial packages expect bad things to happen.
