Hey there,

I mangaged to install Linux ubuntu. There is noch GUI. How do I get the machine start computing? I tried commands from here (sorry german) https://www.seti-germany.de/wiki/Boinccmd but I don't know how to really start it.

There's several things:

1) Wait until some Linux models are available.
2) Make sure that none of the many Suspends are in use.

3) While you're waiting, make sure that the necessary 32 bit libraries are installed.
See: this post for installing.

Not sure where you are at on this. Did you run this command for 32bit compatibility?

sudo apt-get install lib32ncurses5 lib32z1 lib32stdc++-6-dev

If you installed boinc from the Ubuntu repository, I think the boinc service starts automatically when it boots up. I see in the listing in your message that the URL is http://climateprediction.net
I'm not sure if this is the problem, but the URL to attach to should now be https://climateprediction.net/

Even if all that is okay, right now there is no work for Linux, although there should be some more later this week.

If your desktop is on the same subnet as your server you can edit /etc/boinc-client/gui_rpc_auth.cfg and /etc/boinc-client/remote_hosts.cfg to allow remote access via the BOINC Manager GUI software.

There will be new Linux work to download within a week.

Just two things to add.

https://www.cpdn.org/server_status.php which you can find under the drop down menu by clicking on "Computing" near the top of the page will tell you when there are tasks available.

The second thing is, the most likely work for Linux to come out next is a batch of N216 models. The limiting factor here is level3 cache memory rather than RAM in your case. It might be worth keeping an eye on how these models pan out and possibly run fewer than 12 tasks at once.
