[Bug 1640318] Re: /usr/lib/update-notifier/package-data-downloader:OSError:process_download_requests:/usr/lib/update-notifier/package-data-downloader at 305:process_download_requests:print_exc:print_exception

+                        except OSError as e:
+                            if e.errno == 5:
+                                pass

This check makes little sense -- if errno is 5 or something else, the
exception is ignored in both cases. So just

   except OSError:
      pass

is sufficient IMHO -- after all, what else can you do, you can't even
print a warning :-)

Bug description:
  Impact
  ------
  Crash reports are being generated when update-notifier is trying to print a message which isn't really necessary to print.  This crash its reporting process is wasting resources of users and the Error Tracker.

  Test Case
  ---------
  We haven't figure out exactly how the crash is happening but given the volume of errors which we are receiving we can verify it the crash is no longer occurring by checking the errors bucket in this bug report after a couple of weeks.

  Regression Potential
  --------------------
  Its possible that there is something terrible causing stdout to disappear and that we are hiding that by no longer printing when it isn't there.  However, there is insufficient information in the crash reports to sort out why its not available and we'd rather conserve resources by not causing the crashes.

  Original Description
  --------------------
  The Ubuntu Error Tracker has been receiving reports about a problem regarding update-notifier.  This problem was most recently seen with package version 3.172, the problem page at https://errors.ubuntu.com/problem/140b42227c613c32a42f8ad1d4537e8f3dd82dc2 contains more details, including versions of packages affected, stacktrace or traceback, and individual crash reports.
