** Description changed:

+ 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.
  
  This needs to be done in groovy and SRUed to focal.
