Controllers have different versions

After a recent upgrade from v2.x to v3.1 (on deb), my dev instance occasionally reports that my controllers are on different versions. The region controller has a “1:” in front of the 3.1 versioning; the rack controller doesn’t. Can someone tell me what that means? I’m sure it’s something simple that I’m missing.

Hi, could you please paste the output of dpkg -l | grep maas from both controllers?

Thanks!

We’ve found the issue, and it will be fixed in MAAS 3.2.

The 1: comes from the debian package and indicates the epoch of the package version.
