Upgrade hangs during search for obsolete software

[swajime]

My computer asked me if I wanted to upgrade to 16.04, and I clicked yes.
The upgrade stalled in the "Cleaning up" step.
It says "Searching for obsolete software" and the terminal text displays this:

...
173 new root certificates were added to your trust store.
Import process completed.
Done
done.

The window greys out for a few seconds, then becomes active again for a few seconds, over and over again.

$ cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.04
DISTRIB_CODENAME=xenial
DISTRIB_DESCRIPTION="Ubuntu 16.04.1 LTS"

$ uname -a
Linux desktop 3.13.0-96-generic #143-Ubuntu SMP Mon Aug 29 20:15:20 UTC 2016 x86_64 x86_64 x86_64 GNU/Linux

What should I do to finish the upgrade?

Update:

An untimely power failure occurred whilst waiting for an answer. :-(
Fortunately, the system started up ok.

The only problem I noticed so far was that Eclipse quit running. It could no longer find JDK 7, as it was replaced with JDK 8 during the upgrade. I reran the install script for Eclipse and now it is running ok.

I'm still curious to know if there is anything else that should be done.

Thanks,


John

Hmmm....

So, I've rerun the Eclipse install script, reinstalled EPIC, and reinstalled libpadwalker-perl. But the debugger in Eclipse for Perl is no longer working. Pressing the debug icon has no effect. It does not even switch to the Debugger perspective.

Ack :-(

Removed cpp-mars directory altogether and reinstalled. Debug works now. :-)
