# Cadabra 2.2.0 quits without warning on ubuntu 16.04

I'm assuming this is with the binary package? Can you run cadabra2-gtk from the command line and let me know if that spits out any error?

Yeah. The error it showed was "segmentation fault-cored dumped" and the graphical interface closed.

Do you have any left-over cadabra files from a previous install from source in

/usr/local/lib/
/usr/local/bin/

You need remove these, e.g. with

sudo rm /usr/local/lib/*cadabra*
sudo rm /usr/local/bin/cadabra*

before the binary package will work.

I checked and couldn't find any leftover cadabra files. I will uninstall and reinstall it and let you know if I run into such error again.

Is it still crashing or has the problem disappeared?

Yeah, its still crashing. For the time being I am using Cadabra1. Will translate back the code to Cadabra2, after the next update. Thanks.
