Hey all,
Running on the 4.2 branch I am getting the following exception (see
attached backtrace): exceptions.RuntimeError:
twisted.internet.addressalready loaded, cannot load required backport
This is repeated over and over again in the error log. I see that this
is trigggered when call runtime patching the twisted library. I do not
have the system python twisted library installed and I do not have a src
install of the twisted lib. Only the one that gets installed when
running: run.sh -i /
Later on down in the input I also get the following exception (see
second backtrace): exceptions.AttributeError: 'module' object has no
attribute 'backport'
Further on down in the file I get the following the help dump from
twistd and the following message: /usr/local/bin/twistd: Unknown
command: caldav
Any help is appreciated.
Sincerely,
Dennison Williams
