Status changed to 'Confirmed' because the bug affects multiple users.

Get that issue after having changing "trusty" to "utopic" inside /etc/apt/sources.list
In factthat trouble is often met with a new release cycle :

/usr/share/python-apt/templates/Ubuntu.info

is simply not aware of "utopic"; Ubuntu.info needs to be upgraded with the whole "utopic" blocks, after the "devel" blocks and before the "trusty" blocks.

So that also means that "devel" ignore "utopic" right now. As a result, synaptic -> repositories cant be opened to set our preferences. Changing "utopic" by "devel" inside sources.list does not allow synaptic to open the "repositories" to select what we wanting.

[dino99 (9d9)]

Fixed by the python-apt 0.9.3.6 upgrade

Error: could not find a distribution template for Ubuntu/zesty
after changing "yakkety" to "zesty" inside /etc/apt/sources.list
note: from terminal apt-get update and upgrade works fine

[John Russell (jrussell-88)]

Just upgraded to Yakkety amd64, changed 3rd party sources to Yakkety, updated software and software-properties-gtk returns the error:

aptsources.distro.NoDistroTemplateException: Error: could not find a distribution template for Ubuntu/zesty

There is no Zesty in my sources but /etc/lsb-release is:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=17.04
DISTRIB_CODENAME=zesty
DISTRIB_DESCRIPTION="Ubuntu Zesty Zapus (development branch)"

So I edited it:
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=16.10
DISTRIB_CODENAME=yakkety
DISTRIB_DESCRIPTION="Ubuntu 16.10"

And Software & Updates is working again.

I just did the same as John Russel, edited /etc/lsb-release to 16.10, and now it works again.
