Installation error with bird2 from ppa:cz.nic-labs/bird on Ubuntu 1804

It looks like the example file wasn't decompressed during the installation.

Sorry, I might have posted in the wrong place. I've opened too many tabs and messed up a little.

Thank you for taking the time to report this bug and helping to make Ubuntu better.

Unfortunately, we cannot work on this bug because your description didn't include enough information. You may find it helpful to read "How to report bugs effectively" http://www.chiark.greenend.org.uk/~sgtatham/bugs.html. We'd be grateful if you would then provide a more complete description of the problem.

We have instructions on debugging some types of problems at http://wiki.ubuntu.com/DebuggingProcedures.

At a minimum, we need:
1. The specific steps or actions you took that caused you to encounter the problem.
2. The behavior you expected.
3. The behavior you actually encountered (in as much detail as possible).

Thanks!
