This is an unfortunate consequence of a decision by Google to restrict access to the sync API to Chrome only (which explains why in comment #3 you're seeing that chrome 89 on linux works fine).
There's a lengthy discussion with details here: https://groups.google.com/a/chromium.org/g/chromium- packagers/c/SG6jnsP4pWM/m/Y73W4CecCQAJ. I am quoting the part that's relevant for end users: « What does this mean for my users? Users of products that are incorrectly using these APIs will notice that they won't be able to log into their Google Accounts in those products anymore. For users who accessed Google features (like Chrome Sync) through a 3rd- party Chromium-based browser, their data will continue to be available in their Google Account, and data that they have stored locally will continue to be available locally. As always, users can view and manage their data through Google Chrome, Chrome OS, and/or on the My Google Activity page, and they can also download their data from the Google Takeout page, and/or delete it from this page. » I'm afraid (and sorry) there's nothing that can be done from a packaging perspective to mitigate this regression. Reverting the snap in the stable channel wouldn't help, because it's not a version problem. The official announcement states that starting March 15 attempts to log in will fail anyway. I suppose that users that can't do without the profile sync feature will need to move on to using the official chrome package distributed by Google, instead of chromium (which is probably what Google wants, really). ** Changed in: chromium-browser (Ubuntu) Status: Confirmed => Won't Fix -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to chromium-browser in Ubuntu. https://bugs.launchpad.net/bugs/1917705 Title: "profile will be deleted" at startup after chromium 89 update Status in chromium-browser package in Ubuntu: Won't Fix Bug description: After updating the chromium-browser snap from 1497 to 1506, Chromium refuses to work with profiles that are linked to Google accounts. Each of them is deleted whenever first opening it. And turning on profile synchronization does not work. See the attached file for a screenshot of the issue. Workaround: 1. Kill the current chromium process. 2. Revert the snap back to an older version. Warning 1: Running on an older version of Chromium comes at its own issues. Warning 2: Any already deleted profile will not be restored by going back to an older version of Chromium. You will have to create and link the profile again. This bug is severe and means that Chromium has become unusable in a professional environment. "We also need:" 1) The release of Ubuntu you are using $ lsb_release -a No LSB modules are available.

Existing profiles from older versions of Chromium that are linked to sync with a Google account are deleted upon start, and the feature of linking a profile to a Google account for syncing is broken.
