I'm Polish, and I support using native languages, but it's fact - English is the lingua franca of software.
About Linux - internationalization is done right here, in normal day to day usage it isn't needed to know English, but still the problem is with troubleshouting - the easier to google error message the easier it is to solve problem, and error messages in Polish are harder to google.
In old times every error presented to user had an error code, that was constant across locales. I think this is very good convention - it helps with searching for informations about error without enforcing people to use software in locale that is not their native.
BTW - other good convention for error messages is to include in every error message unique string that is also dumped to logs. That way it is later easier to match stacktraces in log files with error reports from users.
Też jestem Polakiem, ale zyję w San Francisco USA.
If you post your error codes online in Polish, then others can find it in Polish... meaning you lower the barrier to entry for other Polish users (one less thing to learn).
The answer is not to require everyone to use English, the answer is to post more about computers in your native tongue.
