#129 Regression: mock in Fedora CI jenkins no longer works: Failed to register machine: Connection timed out
Closed by churchyard. Opened by churchyard.

Closed
Reopen Issue

We run mock builds quite successfully on Fedora CI (both Jenkins and Zuul).

Currently, the setup stopped working on rawhide, Jenkins.

See https://src.fedoraproject.org/rpms/pyproject-rpm-macros/pull-request/66

The command and error is:

Failed to register machine: Connection timed out

I recently hit a similar issue with mock in Jenkins on a different project. The recommendation from the mock devs was to add --no-bootstrap-chroot to the mock command for systems using mock versions >= 2.1.

I added a block to my runner script to just grep the 'mock --help' output for the --no-bootstrap-chroot option and if it is there, use it.

All supported Fedoras have mock 2.4, so --no-bootstrap-chroot should work everywhere, but I wonder why it is needed, when it wasn't needed before.

It seems that the workaround does not work. See https://src.fedoraproject.org/rpms/pyproject-rpm-macros/pull-request/74

The error in this case is:

This problem is gone.
