ok, thank you, I will try and figure it out, for some reason I am not able to figure out were/how to download and install, the link at jens sends me back to this forum for nightlies
That's not correct or your system/browser is totally broken.
As far as I know, there is no link to the nightlies subforum on my server, but a detailed instruction how to add my repo to apt's sources, so you can install a recent version on your system.
Don't forget to read the note for ubuntu users!
If you want to install a nightly of the debugger-branch, follow the (additional) instructions
