[SOLVED] Problem updating (can't connect to repo)

I had bodhi 5 running on an old zotac htpc and gave it to my parents just to run kodi. I got the thing back a few days ago. Everything was running fine. No updates had been applied for a good while though. So I tried to do that at my place. Something went wrong, moksha doesn't start any more, but when I hit ctrl + alt+F2, I can login. I just want to update the system. For some reason however, the PC can't connect to the bodhi repo (“W: Some index files failed to download.”). I compared /etc/apt/sources.list to my other two running bodhi instances, everything is identical... I can ping google, and there are no problems with the ubuntu repos. I want to avoid installing bodhi again, I've already tried, but the BIOS und UEFI on this machine are a nightmare and I can't figure out how to get that done (when I installed bodhi first, I had to do that on an identical zotac and clone the hard drive). So, any help would be much appreciated
