Trouble-shooting
- ImportError: No module named pygtk
- You need to install the python-gtk2 package (the name may vary on different distributions; python-gnome2 is another possibility.
- ImportError: cannot import name cli
- You've probably just upgraded your system from Python 2.3 to Python 2.4 (or similar). Simply install the injector again to fix it.
If the injector isn't doing what you expect, run it with logging turned up using either -v (verbose) or -vv (very verbose!). Use -c to prevent it switching to GUI mode too. Eg:

In the example above, the injector ends up using my local CVS copies of both Edit and ROX-Lib. Here are some known problems, and their solutions:
- Forbidden: header 'Content-Type' value denied (firewall mis-configuration)
- Failed to extract archive; exit code 512 (incorrect environment setting)
- TypeError: iterable argument required (badly formed http_proxy setting)
- gpg: no valid OpenPGP data found (check proxy configuration and 0launch version)
If you get other download errors, try fetching the failing URL using wget, e.g.:
$ 0launch http://... Error downloading 'http://osdn.dl.sourceforge.net/sourceforge/zero-install/injector-gui-0.16.tgz': HTTP Error 403: Forbidden: header 'Content-Type' value denied $ wget http://...
If wget also fails, try opening the URL in your web browser. If one of these works, but 0launch doesn't, it may be that you are using an HTTP proxy. Your web browser is configured to use it, but your http_proxy environment variable is not set. Check your browser configuration and ensure that http_proxy is set correctly, e.g.:
$ export http_proxy=http://myproxy.server:444 $ 0launch http://...
If you still have problems, please write to the mailing list, and send the output of the commands above.
