Before you submit bug reports: https://vdirsyncer.pimutils.org/en/stable/contributing.html
Things to include in your bugreport:
- Your vdirsyncer version
- If applicable, which server software (and which version) you're using
- Your Python version
- Your operating system
- Your config file
- Use
vdirsyncer -vdebug
for debug output. The output is sensitive, but please attach at least the last few lines before the error (if applicable), censored as necessary. This is almost always the most useful information.
