Subject: upgrade from stable to testing fails when configuring python-newt
Package: python-newt
Version: 0.52.2-9
Severity: important
*** Please type your report below this line ***
I started upgrading a system from sarge to etch. The upgrade failed due to:
Setting up python-newt (0.52.2-9) ...
Traceback (most recent call last):
File "/usr/bin/pycentral", line 1373, in ?
main()
File "/usr/bin/pycentral", line 1367, in main
rv = action.run(global_options)
File "/usr/bin/pycentral", line 870, in run
requested = pyversions.requested_versions_for_runtime(pkg.version_field,
version_only=True)
File "/usr/share/pycentral-data/pyversions.py", line 162, in
requested_versions_for_runtime
old = old_versions(version_only=True)
File "/usr/share/pycentral-data/pyversions.py", line 62, in old_versions
return [v[6:] for v in _old_versions]
TypeError: iteration over non-sequence
dpkg: error processing python-newt (--configure):
subprocess post-installation script returned error exit status 1
dpkg --configure --pending gives the same problem.
It looks as if _old_versions is null. The function is:
_old_versions = None
def old_versions(version_only=False):
global _old_versions
if not _old_versions:
if os.path.exists('/usr/share/python/debian_defaults'):
from ConfigParser import SafeConfigParser, NoOptionError
config = SafeConfigParser()
config.readfp(file('/usr/share/python/debian_defaults'))
try:
value = config.get('DEFAULT', 'old-versions')
_old_versions = [s.strip() for s in value.split(',')]
except NoOptionError:
_old_versions = []
if version_only:
return [v[6:] for v in _old_versions]
else:
return _old_versions
If /usr/share/python/debian_defaults does not exist then this code gives the
above error. That is part of python_minimal, which is not installed on this
machine.
The dependencies needs to be fixed so that python-minimal is installed
before python-newt is configured, and/or to deal properly with the missing
/usr/share/python/debian_defaults.
