I tried opening Mendeley through my terminal and got a bunch of errors and a pop-up window that says
Mendeley Desktop is already running but may not be responding. Click the Mendeley icon in the taskbar or dock to activate it.
But there's nothing in the taskbar/dock to click on. The terminal errors I get are:

I followed the advice from this post Why is QsslSocket working with Qt 5.3 but not Qt 5.7 on Debian Stretch? and now I have less errors

http://forums.debian.net/viewtopic.php?f=10&t=131578 makes similar suggestions, along with making sure libcrypto.so and libssl.so are installed - but I can't work out how to install them? It seems like they should be a part of libssl1.0-dev which is now installed..?
Thanks for any advice :)
