Re: Downgrading specific packages with apt

Few days ago I upgraded Google Chrome from version 58 to 59:
google-chrome-stable:amd64 (58.0.3029.110-1, 59.0.3071.86-1)
This new version no longer supports HiDPI. As a result everything in Chrome is
so small that I would need a magnifying glass!

Not a great issue though, since I usually work with Chromium, not Chrome. But
today apt has proposed the very same upgrade for Chromium too:

chromium/testing 59.0.3071.86-1 amd64 [upgradable from: 58.0.3029.96-1]
chromium-driver/testing 59.0.3071.86-1 amd64 [upgradable from: 58.0.3029.96-1]
chromium-l10n/testing 59.0.3071.86-1 all [upgradable from: 58.0.3029.96-1]
chromium-shell/testing 59.0.3071.86-1 amd64 [upgradable from: 58.0.3029.96-1]

I suspect if I upgrade I would end up having the same HiDPI issue with
Chromium. So for the time being I have put on hold those four packages. But
I'd like to test whether this is true. What should I do to be able to
downgrade to version 58.0.3029.96-1 in case 59.0.3071.86-1 does in fact break
HiDPI? I always have some difficulties when I need to downgrade with apt. This
time I want to be prepared.


I've never downgrade using apt, but with synaptic it's not too hard, just go to the menu, package, force version and then to edit, fix packages. The fix package part really only checks to see no package is broken, but you must do it or risk losing all your current settings and have to start over.

Hope that helps.
