Just installed 4.3.0 and now won't start

[Russell Cutcliffe]

Hi, I just upgraded to Weewx 4.3.0 via apt upgrade in

Ubuntu 20.04.1, and now Weewx isn't starting.

Syslog gives this:

$ sudo weewxd --config /etc/weewx/weewx.conf

I'm using the interceptor driver (with indifferent results of late) but it was running, at least before the upgrade.

Hopefully I'm missing something simple..

Any ideas?

Hi,

You might want to have a look at this thread. V4.3.0 is a little more fussy about field interval.

Yep, that fixed it.

Now to fix the startup issue that's appeared...

We can't help without seeing logs to see what 'issue' you are referring to.

I know you're on ubuntu, but I wanted to pass along one edge case I noticed yesterday.  If you're on CentOS and have selinux=enforcing, it is possible that your weewx won't start successfully, depending on how you chose to install it.   On the CentOS platforms, I just set selinux to disabled and it all works fine.   Not the right thing if I ran a real CentOS site of course, but given I just fiddle occasionally LAN-only in Vagrant/VirtualBox I thought I'd take the easy way out.  Bottom line of course is understand your os and check all your logs with debug=1 enabled for debugging.
