I can't convert weewx multi back to a simple weewx.
I have replaced /etc/default/weewx-multi with weewx
WEEWX_PYTHON=python3
WEEWX_PYTHON_ARGS=
WEEWX_BINDIR=/usr/share/weewx
WEEWX_BIN=/usr/bin/weewxd
WEEWX_CFG=/etc/weewx/weewx.conf
also copied the multi-weewx.conf to weewx.conf
What is still missing?
