Well, if running */usr/bin/python3 -V*
gives you Python 3.5, while *python -V* gives you Python 3.7, the problem must be either a path issue, or a symbolic link issue. 1. Make sure it isn't a path issue. What does *which python* give you? Should be /usr/bin/python. 2. Assuming that's the case, what does *ls -l /usr/bin/python** give you? 3. One of the entries should be something like /usr/bin/python3.7. Assuming that's the case, changing the first line of /home/weewx/bin/weewxd so it reads #!/usr/bin/python3.7 should fix the problem. -tk On Wed, Aug 26, 2020 at 8:34 PM weather list <dan.hinck...@gmail.com> wrote: > On 26 Aug, 2020, at 22:05, Tom Keffer <tkef...@gmail.com> wrote: > > > You're making it tough to debug because you're giving so little > information and giving us very short log excerpts. > > > Will remedy that; meanwhile, answers below. > > 1.
