Title:
Bump package epoch to 1 to ensure working upgrade path and transition
to snap
Status in chromium-browser package in Ubuntu:
Fix Released
Status in chromium-browser source package in Focal:
Fix Released
Bug description:
As a follow-up to bug #1889106, it was decided that the best solution to
handle recurring version bumps for chromium-browser updates in stable series
was to bump the package epoch to 1.
See the discussion in
https://lists.ubuntu.com/archives/ubuntu-devel/2020-August/041127.html.
This needs to be done in groovy (done) and SRUed to focal.
[Impact]
Users upgrading from 18.04 to 20.04 will not get the latest chromium snap
replacing the chromium-browser deb package as intended as soon as a security
update is published to bionic-security (which happens typically every 2-3
weeks).
This is because the version number in 18.04 often ends up being greater than
the version in 20.04. Bumping the version number in 20.04 is enough to fix
this, and was done a few times already (bug #1858500, bug #1889106), but it is
tedious and impractical.
[Test Case]
* Ensure that a version of chromium-browser newer than
84.0.4147.105-0ubuntu0.20.04.1 is available in bionic-{security,updates} (not
currently the case, but will soon happen as version 85.0.4183.83 was just
released upstream)
* 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.
[Original Description]
For a complete rationale, see comments #4, #5, #7 and #8 in bug
#1889106, and the discussion in https://lists.ubuntu.com/archives
/ubuntu-devel/2020-August/041127.html.
