I cannot reproduce this error when testing the upgrade scenario in a clean eoan VM where the snap was already installed (tested both with the password-manager-service interface previously connected, and not).
That snapd error looks suspicious, it's as if the core snap wasn't available on your system. See https://github.com/snapcore/snapd/blob/master/interfaces/repo.go#L487. Can you reliably reproduce the error? What's the output of `snap connections core | grep password` ? ** Changed in: chromium-browser (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1838821 Title: [deb2snap] Upgrade fails when snap is already installed Status in chromium-browser package in Ubuntu: Incomplete Bug description: I have the chromium-browser snap installed, and when upgrading to the new snap-based Chromium deb, it fails when the snap is already installed: Preparing to unpack .../chromium-browser_76.0.3809.87-0ubuntu1~snap1_amd64.deb ... => Installing the chromium snap ==> Checking connectivity with the snap store ==> Installing the chromium snap snap "chromium" is already installed, see 'snap help refresh' => Snap installation complete => Connecting the password-manager-service interface (LP: #1836616) error: cannot resolve connection, slot snap name is empty dpkg: error processing archive /var/cache/apt/archives/chromium-browser_76.0.3809.87-0ubuntu1~snap1_amd64.deb (--unpack): new chromium-browser package pre-installation script subprocess returned error exit status 1 Preparing to unpack .../libidn2-0_2.2.0-1_amd64.deb ...
