I wanted to update to 0.12.5, however an
apt-get update causes problems:
W: Failed to fetch http://apt.syncthing.net/dists/syncthing/release/binary-amd64/Packages Hash Sum mismatch W: Failed to fetch http://apt.syncthing.net/dists/syncthing/release/binary-i386/Packages Bad header line [IP: 126.96.36.199 80] E: Some index files failed to download. They have been ignored, or old ones used instead.
Is this a temporary problem?
