I'm normally using Kubuntu (Plasma session) and had this problem. I've run "snap connect chromium:password-manager-service" and it helped.
However, if I log out, and choose the default Ubuntu (Gnome session) and try to use Chromium, it's again without passwords, and re-running "snap connect chromium:password-manager-service" does not help. Please advise how to get the lost passwords back in that case. # apt policy chromium-browser chromium-browser: Installed: 77.0.3865.120-0ubuntu1.19.10.1 Candidate: 77.0.3865.120-0ubuntu1.19.10.1 Version table: *** 77.0.3865.120-0ubuntu1.19.10.1 500 500 http://jp.archive.ubuntu.com/ubuntu eoan-updates/universe amd64 Packages 100 /var/lib/dpkg/status 77.0.3865.120-0ubuntu1~snap1 500 500 http://jp.archive.ubuntu.com/ubuntu eoan/universe amd64 Packages # snap connections chromium | grep password password-manager-service chromium:password-manager-service :password-manager-service manual -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1849160 Title: after deb->snap transition, chromium no longer sees local password store To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/chromium-browser/+bug/1849160/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
