After update to latest wordpress admin is slow

Hi

I have a virtual ubuntu 14.4 and do a clone and try to upgrade to the latest wordpress I get a error when updating the network and admin sites turn extreamly slow

I get this

Varning! Ett problem uppstod vid uppdatering av http://hublog.se/frontend. Din server kanske inte kan anslut mot webbplatser på den. Felmeddelande: Failed to connect to hublog.se port 80: Connection timed out

The swedish part is:
Warning! A problem has accured during update on http;//hublog.se/frontend. Your server cannot connect to websites on it. Error: Failed to connect to hublog.se port 80: Connection timed out

I moved back to the orginal clone so the the updated server is not this one so the issue can not be found here.

Any ideas?

regards Hubbe

any ideas on this one.
