Zypper dup to 42.2 has stalled. What to do now?

Strange, I updated everything and only had the four required repos enabled for 42.2. Ran:-

zypper ref && zypper dup

and went away to get on with something else. Came back and found the process has stalled almost as soon as it started, the last few lines being:-

Retrieving package texlive-arydshln-doc-2015.104.1.71svn15878-21.16.noarch
                                                                       (60/4437), 530.4 KiB (623.7 KiB unpacked)
Retrieving: texlive-arydshln-doc-2015.104.1.71svn15878-21.16.noarch.rpm ------------------------------starting^

60 out of 4437 isn’t much progress. My question is, what should I do now? I don’t want to break the existing 42.1 installation which I am using for this message.
Grateful for some guidance please>

Whilst waiting for guidance and getting on with other work the system timed out and retried and now all is running again.

Some problem with the repo system I assume.

Nice it recovered before we all are trying our thinking power on this rotfl!
