Yeah, this the less common path where it tries to warn you if your current working directory is /etc/apt because generating a new sources.list file would overwrite the existing file. Running the script from a different working directory should avoid the error. Must have been introduced in a previous refactor, and wasn't caught because 1. there are no unittests 2. I have not manually tested this non-critical path for a while. Code fix is pretty clear. Would welcome a pull request or will try to find some time to fix and release with #76

Easy enough to work around in that case :)

I don't expect to be able to create a pull request any time soon but I'm not ruling it out. I still have quite a few issues of my own to solve as well: https://github.com/issues?utf8=%E2%9C%93&q=is%3Aopen+user%3AWoLpH
