Thanks for the pointers, etc. Matthew. I did what you suggested with the
dependencies, etc., and all went well (as in no errors upgrading
reported.) Also, as you said, I changed /etc/weewx/default from:
WEEWX_PYTHON=python2
WEEWX_BINDIR=/usr/share/weewx
WEEWX_BIN=/usr/bin/weewxd
WEEWX_CFG=/etc/weewx/weewx.conf
--- to --
WEEWX_PYTHON=python3
WEEWX_BINDIR=/usr/share/weewx
WEEWX_BIN=/usr/bin/weewxd
WEEWX_CFG=/etc/weewx/weewx.conf
However, starting it with:
weewxd /etc/weewx/weewx.conf
Gives the following error:
Traceback (most recent call last):
File "/usr/share/weewx/weewxd", line 261, in <module>

except KeyError, e:
^
SyntaxError: invalid syntax
I *think* I am missing something subtle, but I can't figure it out. Any
further suggestions? I went with your post instead of Tom's for now
regarding starting it because I didn't want to introduce yet another
variable. Either way, does that error tell you anything? I didn't touch
my config files or anything else. I can post them if you think they'd be
useful. Probably unrelated, I'm using your sftp extension. Everything
works fine with Python 2.7.
I put it back to weewx 4.1.1 using python2 from my SD backup. All works
fine, except that I'm no farther ahead . . . still using python 2.7.
