The next problem came when I tried to build the HTML for this site.
Traceback (most recent call last):
File "/home/hades/.virtualenvs/necromuralist.github.io/bin/nikola", line 5, in <module>
from nikola.__main__ import main
ModuleNotFoundError: No module named 'nikola'
For some reason the nikola executable was missing. Since I was in a virtual environment I tried to re-install nikola but using pip gave another error.
Traceback (most recent call last):
File "/home/hades/.virtualenvs/necromuralist.github.io/bin/pip", line 5, in <module>
from pip._internal.cli.main import main
ModuleNotFoundError: No module named 'pip'
So, not only was nikola missing but so was pip, which I thought was a part of the python installation… I looked at what was in the virtualenvironment -
ls ~/.virtualenvs/necromuralist.github.io/lib
And saw that it had this python version:
But when I checked the version of the python I was using it gave this.
So it looked like the ubuntu update created a bit of a mismatch. It turns out that virtualfish has a command to list what virtual environments you have set up (vf ls) and if you pass it the --details= option it will show you the python version the environment is using.
It listed all my environments but in particular it showed this for the environment for this site's repository.
necromuralist.github.io (broken)
virtualfish also has a command to upgrade the currently active environment so I tried running it.
Running this with the necromuralist environment active:
Gave this error.

note: This error originates from a subprocess, and is likely not a problem with pip.
Which looked like I was in trouble, but it turned out that re-running the upgrade fixed it. One of those magic fixes that would be scary if this was a critical site, I suppose, but which is instead, just another bit of python mystery.
