  • The version does not matter; you just got to adjust the commands to "trusty" if there is any numbering involved.

To solved it,

First Step
Check all package source using:

rgrep 'xenial' /etc/apt

cause i used trusty instead xenial, so i remove all sources that of snapd* using

sudo add-apt-repository -r 'deb [some link xenial] xenial Release or inRelease'

Next Step

and i can purge and remove snapd to solved that.

dpkg --purge --force-all snapd
sudo apt install --fix-broken

run sudo apt-get update,after updated it's solved to me.
