Unfortunately, the buildbot has been unreachable since my problems began. I have stripped my sources.lists down to just the buildbot: deb http://buildbot.linuxcnc.org/ jessie master-sim deb-src http://buildbot.linuxcnc.org/ jessie master-sim but sudo apt update returns: Err http://buildbot.linuxcnc.org jessie InRelease Err http://buildbot.linuxcnc.org jessie Release.gpg Could not resolve 'buildbot.linuxcnc.org' Reading package lists... Done Building dependency tree Reading state information... Done All packages are up to date. W: Failed to fetch http://buildbot.linuxcnc.org/dists/jessie/InRelease W: Failed to fetch http://buildbot.linuxcnc.org/dists/jessie/Release.gpg Could not resolve 'buildbot.linuxcnc.org' W: Some index files failed to download. They have been ignored, or old ones used instead. The web page is there at buildbot from this machine, but Damn if network-mangler hasn't re-written the /etc/resolv.conf with a blank file. First is nuke resolvconf, rewrite a good /etc/resolv.conf, make sure it works and sudo chattr +i /etc/resolv.conf. Done. Now the buildbot responds and tells me linuxcnc is all up to date. > > > > Yeah, I should be able to use the armhf builds if I'm running stock > > Debian (which works on the RPi 2 & 3).
