Re: [Discuss-gnuradio] ImportError: No module named ...

[Marcus Müller]

Glad to have you here, too!

Just a word of advice: this is not a linux support channel. We really
like being helpful, so it's ok to ask things related to GNU Radio and
the system it runs on, but if you want linux help, you might want to go
online in IRC and join the #ubuntu channel on irc.freenode.org , using
either a desktop client of your choice (e.g. Pidgin) or the web client
at http://webchat.freenode.net/


Greetings,
Marcus
