[Impact]
Crashes of gdebi (and possibly other tools) in non-English locales which use 1,0 or similar instead of 1.0

[Test case]
Install a deb package with gdebi, like Google Chrome, in such a locale.

Original: Gdebi crashed while installing Google Chrome .deb-fil bur the error didn't appear until I logged out and back in again

[Regression potential]
Same as bug 1611010 - very low.

The traceback actually seems to be in python-apt.

  File "/usr/lib/python3/dist-packages/apt/progress/base.py", line 255, in update_interface
    if float(percent) != self.percent or status_str != self.status:
ValueError: could not convert string to float: '0,0000'

Julian K indicated that the fix for 1611010 might end up fixing this and that he'd look at cherry-picking into into Ubuntu 16.04.

[Julian Andres Klode (juliank)]

Let's clean this up.

apt 1.2.16~rc1 just hit the PPA (might take some time for processing, though):

  https://launchpad.net/~deity/+archive/ubuntu/apt-1.2

and should fix this bug. It would be great to have some confirmation of that before uploading that, otherwise I'll go ahead with an SRU tomorrow probably if I don't notice any regression on my system.

[Julian Andres Klode (juliank)]

1.2.16 uploaded.

Hello Jimmy, or anyone else affected,

Accepted apt into xenial-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/apt/1.2.18 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 on 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!

There are a couple of instances of this occurring with 1.2.18, but I think that is just noise as apport doesn't add package version information until the data collection is done which can be a bit after the crash.

This bug is triggered when upgrading up to date xenial to yakkety, so should be showstopper priority.
do-release-upgrade fails and cannot continue, potentially leaving system in unbootable state.
