Looking at the code in:
/usr/lib/python2.5/site-packages/UpdateManager/Core/MetaRelease.py
It seems I had a zero sized METARELEASE_FILE. This was being created by
the __init__ method of MetaReleaseCore:
try:
open(self.METARELEASE_FILE,"a")
except IOError, e:
path = os.path.expanduser("~/.update-manager-core/")
if not os.path.exists(path):
os.mkdir(path)
self.METARELEASE_FILE = os.path.join(path,"meta-release")
Then the download() method checks the mtime of METARELEASE_FILE in order
to add an If-Modified-Since header to the http request. The mtime is
very recent because we just touched it in __init__. Because of this
urllib throws an exception with HTTP 304 Not Modified.
The exception handler then sees the empty METARELEASE_FILE:
except urllib2.URLError:
if os.path.exists(self.METARELEASE_FILE):
self.metarelease_information=open(self.METARELEASE_FILE,"r")
And sets metarelease_information to the newly opened empty file. Later
on a parse is attempted on this file which results in no meta-release
information matching the current distro.
Fix/workaround:
Taking the last-modified check out works, but probably the best thing to
do is to check for a zero sized file at the same time as reading the
mtime.
