I think I jacked up my python install by trying to mess around with virtual environments when I wasn't paying enough attention.
python3 --version
Python 2.7.6
But I'm not sure how this is the case when I check the bin:
ls -lah /usr/bin/python3
lrwxrwxrwx 1 root root 9 Sep 21 2015 /usr/bin/python3 -> python3.4
It's driving me crazy because I can't use apt correctly with this happening. I'm getting ASCII errors because it's using the wrong interpreter.
I'm pretty sure I messed something up with pyvenv or venv, but I'm not sure what. Help?
Okay, I ran dpkg -C and got a whole bundle of half compiled packages. Mostly python3 packages since I tried to remove and reinstall it. I ran dpkg --configure on them and got to one which gave this error:
Setting up python3-gi (3.12.0-1ubuntu1) ...
File "/usr/bin/py3compile", line 4
SyntaxError: Non-ASCII character '\xc2' in file /usr/bin/py3compile on line 4, but no encoding declared; see http://www.python.org/peps/pep-0263.html for details
dpkg: error processing package python3-gi (--configure):
subprocess installed post-installation script returned error exit status 1
Errors were encountered while processing:
python3-gi
This error was appearing before, I suppose, as it is appearing when I try to install other packages now, but is further back in the stack trace.
Full dpkg -C:
