<![CDATA[Opera crashes and will not start after upgrade (48)]]>Opera crashes and will not start since upgrade. Version is given as 48.0.2685.32
Ubuntu (15.10) crash reporter states SIGABRT
It doesn't allow me to copy and paste the crash details, and it appears that I can't include a screenshot here.
Also in the crash reporter is "Unreportable reason - This is not an official Ubuntu package".

Now looking for a way to convert bookmarks to use in Firefox, but Opera won't start to allow me to export them.

However, both are too old now, because all the working repos of ubuntu (14.04, 16.04 and to 17.10) have 3.28 (2:3.28-whatever), so yes, an update is mandatory for you now.

Version: 2:3.23-0ubuntu0.15.10.1
Version: 2:3.19.2-1ubuntu1

In Synaptic it shows the installed version is 2:3.23-0ubuntu0.15.10.1

apt-cache show libnss3 | grep Version

because packages.ubuntu.com does not list your version's packages anymore.

For anyone else having this problem this is what I did (after cd to the above directory):

sudo dpkg -i opera-stable_47.0.2631.80_amd64.deb

This will do for now. I have been intending to upgrade to a newer Linux OS but still need to make sure I have backed up some data which I have not finished doing yet.

Ubuntu 15.10 is unsupported since July 2016

Okay, but it showed the update & allowed me to install it.

Normally you'll see a number of messages anyway, so the output could be pretty long.

You can do screenshots, but you need to upload them to some external site then embed them in your post. At least, until the forum update.

So upgrade to 16.04 at least.

Upgraded an hour ago. Opera (mini) now doesn't work. uninstalled, reinstalled, New one doesn't start, says Can't connect. All other applications fine.
