Thanks. The solution however was a bit different. I downloaded the unifi debian package from their website, removed the mongodb-* dependencies using this website and installed it. Works like a charm until the next unifi controller update.

Hi Igor. Thanks for the hint/confirmation, that this would work. What I did is: I downloaded the package from launchpad and tried installed it using dpkg. But that failed. Is there another way you would recommend?

Understood. I thought you were able to use just the xenial package for mongodb on debian stretch. :-( Meanwhile I was able to install the binaries provided for RPI 3 from this post https://andyfelong.com/2017/08/mongodb-3-0-14-for-raspbian-stretch/ Unfortunately the unifi package cannot be installed because it still thinks that mongodb is not installed. I‘ll guess I‘ll have to figure out how to convince the apt-get system to ignore that dependency.

I'm having the same issue with the unifi/mongodb package after upgrading my cubietruck to debian stretch. Are you able to help us on how to do that? unifi : Depends: mongodb-server (>= 2.4.10) but it is not installable or mongodb-10gen (>= 2.4.14) but it is not installable or mongodb-org-server (>= 2.6.0) but it is not installable

Understood. I've also tried to find a way with pre-installing an armbian in VirtualBox, which led to suggestion of QEMU. But this is way to complicated for me. I might go with a fresh SDCard and try to find out what I've done already on the old installation and then migrate. Thanks. Topic can be closed.

Not the answer I hoped for but maybe the only way to go . Is there a way to save the current running system into a virtual machine with virtual box before doing a clean install? Do you aim with armbian that this won't happen in two years again?

Hello Armbian-Folks, more than two years ago I purchased a CubieTruck and installed Cubian with kernel 3.4.79 on the microSD. The system is running since then and serving as airprint server, boinc client and monitoring device for my internet connection. Basically I use it more or less as a headless server. Now I would like to have this system more future ready and looking for an upgrade path. The kernel is quite old and the distro is based still on debian wheezy. Also Cubian is dead and not maintained anymore. Are you able to help or provide some good starting tipps to upgrade my system to new kernel and maybe armbian (debian jessy) as distro? I was searching the web for the last 2 days to find a suitable howto but couldn't find something usable. It would be awesome if I can find some help here where to start. Many Thanks in advance.
