this issue had already been resolved over IRC. It was not a caching issue, as cache was not used in the failing run at all. The issue was misnaming of a package. 'subrocess32' was used in the '*.packages' file instead of 'python-subprocess32'.

The only way I know to 'invalidate' old pkg in mock is to specify the
version you need in .packages ( i.e >= $ver ).
Otherwise, the mock cache should expire in 2 days.

Please confirm this can be closed as (another) duplicate of

> fail to import the package on some slaves:

This is often the result of the packages not being installable (often because of missing repos) - unfortunately mock ignores that silently because yum does e.g. when doing 'yum install a b c' will not result in an error is 'b' is not installable.

> Do we have a way to invalidate mock cache manually?

The cache is keyed by the checksums of the '*.packages' and '*.repos' files, so changing them invalidates it
