Building on core18, failure on pulling core18 on build.snapcraft.io

I’m building a classic ubuntu-report snap via build.snapcraft.io.

The snapcraft.yaml definition is https://github.com/ubuntu/ubuntu-report/blob/master/snap/snapcraft.yaml, which is using on core18.

However, it can’t build in the lxc xenial container, contrary to 18.04:

It happens also with ubuntu-make.

Any update/hints on that one? This is blocking building the ubuntu-report classic snap to be pushed to the store.

We don’t support using core18 for classic with snapcraft yet, nor do we support building classic snaps in any environment other that one setup on your own.

A roadmap of whens and hows will be shared out next week after we finish doing this cycle’s planning.

5

Additionally, build.snapcraft.io currently only supports core as a base.

6

Well, actually you do support it in snapcraft (locally, it all works fine ;)), but ok, blocked on the build.snapcraft.io side.

7

Yes, locally though, it is still experimental

Is this now fixed, as core18 was something as usable…

I guess I am still seeing the issue today. Would appreciate a hint how to get over it. :wink:
