Yep - looks like it was superseded with that other module shown, the Weatherlink Cloud , great name eh?
I just updated my Linux box to a new, used PC, which required a new install of MariaDB, Python et al and I copied my old WeeWX config on to the new machine, I've not had the problem "Unable to load driver [Err no 113] no route to host." It used to happen when I'd restart the old PC, both machines were/are running Ubuntu 18.04 LTS.
That error required that I pull the plug on the WLIP and restart it, then restart WeeWX. As can happen, this would run well for months, then I'd do an update or something requiring a reboot and have to reset the adapter. I wish I knew exactly which change/update fixed it for me, but there were too many to track.
My experience may be unique, but you have little to lose if you backup your DB and WeeWX config then updated your installs. Never know what else you can break doing that *-).
