Bug Description

On two machines I've upgraded (one from precise another from saucy) the file /usr/share/python-babel-localedata/localedata/en.dat has somehow been deleted. Reinstalling the package resolves the problem.

  File "/usr/lib/python2.7/dist-packages/babel/messages/catalog.py", line 337, in _get_mime_headers
    locale='en')))
  File "/usr/lib/python2.7/dist-packages/babel/dates.py", line 609, in format_datetime
    locale = Locale.parse(locale)
  File "/usr/lib/python2.7/dist-packages/babel/core.py", line 313, in parse
    raise UnknownLocaleError(input_id)
UnknownLocaleError: unknown locale 'en'

Version: 1.3+dfsg.1-2ubuntu1

> dpkg -L python-babel-localedata | grep en.dat
/usr/share/python-babel-localedata/localedata/en.dat
> file /usr/share/python-babel-localedata/localedata/en.dat
/usr/share/python-babel-localedata/localedata/en.dat: ERROR: cannot open `/usr/share/python-babel-localedata/localedata/en.dat' (No such file or directory)

[Impact]

The python-babel package got split into python-babel and python-babel-localedata. There were some upgrade issues which got fixed in 1.3+dfsg.1-2 and 1.3+dfsg.1-2.1. Ubuntu merged the package between those versions and missed the second fix. This SRU backports the changes from 1.3+dfsg.1-3 to the package scripts for python-babel.

[Test case]

- Install the python-babel package from either saucy or precise
- Run "pybabel --list-locales" and get a list of locales
- Upgrade python-babel to the version in trusty (will pull in python-babel-localedata)
- Run "pybabel --list-locales" again and get the above error
- Upgrade to the fixed version
- Run "pybabel --list-locales" again and get a list of locales again

- Purge python-babel and python-babel-localedata (to start from fresh to test an upgrade directly to the fixed version)
- Install the python-babel package from either saucy or precise again
- Run "pybabel --list-locales" and get a list of locales
- Upgrade directly to the fixed version
- Run "pybabel --list-locales" and get a list of locales

Hi Michael

Please could you update the version on the maintainer scripts to align to the SRU version (1.3+dfsg.1-2ubuntu2~), otherwise the migration will be repeatedly triggered for any further SRU's of this package.

Thanks!

James

Hello Tristan, or anyone else affected,

Accepted python-babel into trusty-proposed. The package will build now and be available at http://launchpad.net/ubuntu/+source/python-babel/1.3+dfsg.1-2ubuntu2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested, and change the tag from verification-needed to verification-done. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed. In either case, details of your testing will help us make a better decision.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance!

Verified that I could list locales after upgrading from 0.9.6-1build1 to 1.3+dfsg.1-2ubuntu1 then 1.3+dfsg.1-2ubuntu2

I also verified it was fixed after upgrading from 0.9.6-1build1 directly to 1.3+dfsg.1-2ubuntu2
