Upgrading from 19.04 to 19.10 will keep the 19.04 chromium-browser due to a higher version than the transitional deb in 19.10

[Sønke Lorenzen]

[Impact]

Users upgrading from 19.04 to 19.10 will not get the latest chromium snap replacing the chromium-browser deb package as intended.
This is because the version number in 19.04 is greater than the version in 19.10. Bumping the version number in 19.10 is enough to fix this.

[Test Case]

 * On a machine running 19.04, 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 19.10
 * 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.
 * Version 79.0.3945.79-0ubuntu0.19.10.2 which is being uploaded also contains a couple of minor unrelated changes, but those are harmless. They are included because they were already pushed to the source package's VCS:
   - https://bazaar.launchpad.net/~chromium-team/chromium-browser/eoan-stable/revision/1525
   - https://bazaar.launchpad.net/~chromium-team/chromium-browser/eoan-stable/revision/1526

[Original Description]

19.04 has got a higher version chromium-browser now than the transitional deb package that install the snap version, so the 19.04 version will be kept when someone upgrades since 19.04 got a higher version, and then no further updates.

I uploaded chromium-browser 79.0.3945.79-0ubuntu0.19.10.2 to eoan-proposed to fix this situation, thanks Sønke Lorenzen for noticing and reporting the problem!

[Łukasz Zemczak (sil2100)]

Hello Sønke, or anyone else affected,

Accepted chromium-browser into eoan-proposed. The package will build now and be available at https://launchpad.net/ubuntu/+source/chromium-browser/79.0.3945.79-0ubuntu0.19.10.2 in a few hours, and then in the -proposed repository.

Please help us by testing this new package. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation on how to enable and use -proposed. Your feedback will aid us getting this update out to other Ubuntu users.

If this package fixes the bug for you, please add a comment to this bug, mentioning the version of the package you tested and change the tag from verification-needed-eoan to verification-done-eoan. If it does not fix the bug for you, please add a comment stating that, and change the tag to verification-failed-eoan. In either case, without details of your testing we will not be able to proceed.

Further information regarding the verification process can be found at https://wiki.ubuntu.com/QATeam/PerformingSRUVerification . Thank you in advance for helping!

N.B. The updated package will be released to -updates after the bug(s) fixed by this package have been verified and the package has been in -proposed for a minimum of 7 days.

[Olivier Tilloy (osomon)]

Verified working. I followed the steps in the test case: in a clean disco VM, I installed chromium-browser (and verified that the chromium snap wasn't installed). I then dist-upgraded the VM to eoan, and verified that chromium-browser hadn't been updated, and that the chromium snap still wasn't there. I then enabled eoan-proposed in /etc/apt/source.list, updated, installed the chromium-browser update that was available (79.0.3945.79-0ubuntu0.19.10.2), and the chromium snap got installed, as expected.

[Sønke Lorenzen (solorenzen)]

This worked for me too after enabling eoan-proposed, I have now the snap on that installation.
