@Chad I checked my /var/log/apt/history.log. It showed that the following chromium role-commit-package upgrades were performed:
chromium-browser:amd64 (56.0.2924.76-0ubuntu0.16.04.1268, 57.0.2987.98-0ubuntu0.16.04.1276), chromium-codecs-ffmpeg-extra:amd64 (56.0.2924.76-0ubuntu0.16.04.1268, 57.0.2987.98-0ubuntu0.16.04.1276), chromium-browser-l10n:amd64 (56.0.2924.76-0ubuntu0.16.04.1268, 57.0.2987.98-0ubuntu0.16.04.1276) Also, a day before this upgrade, my kernel was upgraded: linux-headers-generic-hwe-16.04:amd64 (4.8.0.45.17, 4.8.0.46.18) I don't know which adobe-flashplugin I had initially. To fix it, I had to issue the following command: apt-get install browser-plugin-freshplayer-pepperflash -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1680433 Title: Flash: This plugin is not supported.
