Upgrade 16.04 -> 16.10 Synaptic has error

[Arlen_B_Taylor]

After doing an upgrade via Muon Discover from 16.04 to 16.10, Synaptic won't open properly. The error is:

E: The value 'xenial' is invalid for APT: Default-Release as such a release is not available in the sources
E: _cache->open() failed, please report.

Please try:

sudo apt clean
let us know if it works please.

[Arlen_B_Taylor]

Done, it still has the same error.

[wildmanne39]

Please do:

sudo cat /root/.synaptic/synaptic.conf
paste it here by clicking new reply then above the window you click on # and put the information in between the two code boxes

Thanks

Change
Synaptic::DefaultDistro "xenial";
To:

Synaptic::DefaultDistro "Yakkety";
by running:

sudo -H gedit /root/.synaptic/synaptic.conf
The line is at the bottom of the screen.

After you make the change save,close gedit and reboot.
Thanks
