Getting "License check failed! Giving up..." after installing Qt 5.6 through Maintenance Tool
-
A couple of years ago when I first started looking into Qt I had a big issue with the Maintenance Tool. Back then it was actually integrated into Qt Creator itself and every time I tried to start it my system (especially the CPU) went berserk. This - thank Heaven (and the Qt devs ;)) - has been resolved. Approx. 2-3 weeks ago I decided to upgrade my Qt version on my Linux notebook from 5.5 to 5.6. I'm running Debian Jessie 64bit and also have the repository version of Qt installed but also have the 5.5 (the repos don't have recent versions of Qt) from the official source - Qt's download page. It took me some time to find the Qt repository links which I have to add to the Maintenance Tool. You can see the two repositories in the User-defined section at the bottom of the Maintenance Tool:
The problem I'm having is that ever since I updated my 5.5 and also added 5.6 I'm getting:
License check failed! Giving up...whenever I try to build ANY
qmake-based project. I don't have any issues with usingcmakein combination with Qt.Can you help me? It's a real pain and so far I have found just a few related posts on the Internet without any solution and also only Windows-related.
PS: Perhaps not related but when I installed 5.5 using the setup downloaded from Qt's download page I had to manually add the kit to my Qt Creator. This is still the case however the newly installed 5.6 is auto-detected which is great but sort of confusing considering what's going on with 5.5's installation...

Did you install the commercial version of Qt?

They do, but not for the stable flavour. On my stretch the repo Qt version is 5.5.1.
The problem I'm having is that ever since I updated my 5.5 and also added 5.6 I'm getting:
License check failed! Giving up...See also here.
I personally find that maintenance tool a big pain in the neck (for Linux at least) and I just do a developer build from the git whenever I wish version not supplied by Debian.Kind regards.

Thanks for all the replies.
@jsulm, no I insalled the community edition.
@kshegunov Well, I meant Jessie (which is stable) and an upgrade of the whole system just to get the new version of Qt is a little bit of an overkill for me. :D As for the link you pointed in your post - I actually do have to sign in whenever I run the maintenance tool so it's not about missing credentials on my behalf.
Anyway I decided to do a fresh install of Qt SDK and obviously it's working now as intended. I guess the maintenance tool is still very buggy.
Thanks again!
