Comment 3 for bug 1912682

This sometimes causes build errors that are difficult to fix. Retrying the build doesn't help, because the failed "yum install" gets cached by docker.

The real workaround is to re-run "docker build" with "--no-cache" option, but tb.sh doesn't support this.

Other caveats: this command:

   yum install ... http://host/path/to/file.rpm ...

Fails if /etc/yum.conf has "skip_missing_names_on_install=0" --AND-- the reason for the error is HTTP 404. But "host" doesn't respond at all, it's not considered an error.

So a RUN step from dockerfile may get cached and subsequent build attempts will keep failing.

Suggest to increase Importance of this bug.
