Public bug reported:
This bug is another manifestation of bug #1858500, but with a different upgrade
path.
bionic-{security,updates} will soon have chromium-browser
84.0.4147.89-0ubuntu0.18.04.2 (pending sponsoring by the security team), and
when that happens the version number in focal will be lower, meaning that
chromium-browser won't be updated to the new package that installs the snap for
a user upgrading from 18.04 to 20.04.
Since chromium-browser in 20.04 is a mostly empty transitional package
that installs the chromium snap, all that's needed to fix this is to
bump its version number.
[Impact]
Users upgrading from 18.04 to 20.04 will not get the latest chromium snap
replacing the chromium-browser deb package as intended.
This is because the version number in 18.04 is (will soon be) greater than the
version in 20.04. Bumping the version number in 20.04 is enough to fix this.
[Test Case]
* Ensure that chromium-browser 84.0.4147.89-0ubuntu0.18.04.2 is available in
bionic-{security,updates}
* On a machine running 18.04, ensure that the chromium snap is *not*
installed, then install the chromium-browser deb package: sudo apt install
chromium-browser
* Upgrade that machine to Ubuntu 20.04
* When upgrading, the chromium-browser package becomes a transitional package
that installs the chromium snap
* Verify that the chromium snap is installed
[Regression Potential]
* The chromium snap has some known shortcomings and regressions
compared to the deb package, they are being tracked at
https://bugs.launchpad.net/ubuntu/+source/chromium-
browser/+bugs?field.tag=snap. Auto-upgrading users from the deb to the
snap is the desired behaviour though.
