An strace of the appstreamcli process while it's stuck at 100% CPU shows
nothing at all, so it looks like it got stuck in a loop doing
"something" that needs no syscalls...

Title:
Can't "apt-get update" - appstreamcli stuck at 100% Processor
Utilization
Status in appstream package in Ubuntu:
Confirmed
Bug description:
I did a fresh install of Ubuntu 16.04 without being connected to the
internet because when connected to the internet the install would lock
up at the point that ubuntu was "Retrieving 56 of 56".
Installation (without internet) was successful, then I connected to
the internet and tried to update:
The update-process seemed to be stuck, so I discovered that the
command appstreamcli was at 100% processor utilization indefinitely.
When I kill that process the update fails. This is clearly a bug, but
hopefully someone can suggest a work-around until it is fixed.
