lektor server does not start under freebsd

I have installed lektor via freebsd ports, there was no error. lektor quickstart also created my project but after I would like to start lektor server no matter which folder I am in or which flags do I add, I get this error:

Traceback (most recent call last):

I did everything as it was described in quick start, so this is just a default installation. My os version is:

FreeBSD 13.1-RELEASE releng/13.1-n250148-fc952ac2212 GENERIC amd64

And my installed lektor version is:

Lektor, version 3.2.2

How should I fix this? Is that a known bug? I didn't found anything usefull while googleing.

Solution

  • Looks like somebody reported this as a freebsd bug. Appling the fix: https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=263922 will update it to new version of lektor and the server will also work.
