Hello and thank you for filing this bug report.
It seems like you must have some local configuration change, as the
issue is:
Preparing to unpack .../python-cryptography_1.2.3-1ubuntu0.1_i386.deb ...
File "/usr/bin/pyclean", line 63
except (IOError, OSError), e:
^
SyntaxError: invalid syntax
dpkg: warning: subprocess old pre-removal script returned error exit status 1
dpkg: trying script from the new package instead ...
File "/usr/bin/pyclean", line 63
except (IOError, OSError), e:
^
SyntaxError: invalid syntax
dpkg: error processing archive
/var/cache/apt/archives/python-cryptography_1.2.3-1ubuntu0.1_i386.deb
(--unpack):
subprocess new pre-removal script returned error exit status 1
which is not a syntax error in python2, but is in python3. Did you by
any chance change your default python interpreter (/usr/bin/python) to
python3 (not recommended or allowed by PEP).
Can you provide:
apt-cache policy python-minimal
python -V
outputs?
** Changed in: python-cryptography (Ubuntu)
Status: New => Incomplete
