Same on bionic 18.04:
$ python2 --version
Python 2.7.15rc1
$ sudo hp-doctor -i
Traceback (most recent call last):
File "/usr/bin/hp-doctor", line 42, in <module>
check_extension_module_env('cupsext')
File "/usr/share/hplip/base/g.py", line 340, in check_extension_module_env
python_ver = xint((sys.version).split(' ')[0]) #find the
current python version ; xint() to convert string to int, returns a list
File "/usr/share/hplip/base/g.py", line 332, in xint
return l
UnboundLocalError: local variable 'l' referenced before assignment
# Edit: pdb.set_trace()
$ sudo hp-doctor
> /usr/share/hplip/base/g.py(333)xint()
-> return l
(Pdb) ver
'2.7.15rc1'
(Pdb) ver.split('.')
['2', '7', '15rc1']
(Pdb) [int(x) for x in ver.split('.')]
*** ValueError: invalid literal for int() with base 10: '15rc1'
(Pdb)
Code work-around:
# Convert string to int and return a list.
def xint(ver):
try:
l = [int(x) for x in ver.split('.')]
except:
l = []
for x in ver.split('.'):
try:
l.append(int(x))
except:
l.append(None)
return l
$ sudo hp-doctor
error: cupsext not present in the system. Please re-install HPLIP.
# debug info: [2, 7, None]
Solution for me is `python3 hp-doctor` instead:
$ python3 -VV
Python 3.6.5 (default, Apr 1 2018, 05:46:30)
[GCC 7.3.0]

Title:
hp-doctor: UnboundLocalError: local variable 'l' referenced before
assignment
Status in HPLIP:
New
Status in hplip package in Ubuntu:
Confirmed
Bug description:
hp-doctor is trying to parse the Python version. Probably other tools
are too.
On Python 2, sys.version is "2.7.14+", whos parts cannot be parsed as an
integer.
On Python 3, sys.version is "3.6.5rc1", whos parts cannot be parsed as an
integer.
Neither of these will work.

(Note that my printer will only print "Unsupported Personality: UNKNOWN".
This is probably an unrelated problem.)
