Errors with weewx 5.2 and forecast extension

[matt.e...@gmail.com]

I'm trying to install the forecast extension with weewx 5.2. When I restart weewx I'm getting this error immediately. Any suggestions?

Thank you. That did solve my problem.

It’s kind of crazy that forecast still depends on six.  I just published v4.1 with six removed.  It also details how to install xtide since xtide has been removed from current Linux distros.
