I get the same error message when attempting to run grc on Ubuntu Oneiric.

[Dimitrios Symeonidis (azimout)]

This seems to be an old bug with the preferences loading in GRC:
http://www.ruby-forum.com/topic/190977

Temporary workaround (works in Natty):
touch ~/.gnuradio/config.conf
cat /etc/gnuradio/conf.d/grc.conf >> ~/.gnuradio/config.conf

[Noman Akbar (noman-akbar486)]

i am getting the same error.....how can i fix it?

[John Brooks (frogging101)]

I can confirm that this bug exists, and the above fix mentioned by azimout works in Oneiric.

[Adam (i450006)]

I confirm the same problem!

but the solution from Noman (#3) worked for me, thanks!

New instalation of GNU radio. The instalation was confirmed. Pushing the icon causes it to flash but the app doesent start. Ubuntu 18.10 newest gnuradio package.
