As error types are not preserved on the client side (due to marshaling), we cannot use `errors.Cause(...)` and friends but, unfortunately, have to fall back to looking for substring the error messages. Change the error checks in remote run to do substring matches and fix issue #7340. Fixes: #7340 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
