Rolling Back Individual Components?

[skostojohn]

I just had the Cosmic Store apply a bunch of updates to cosmic elements, and suddenly my system is less stable and has a lot of issues.

How can I roll back individual components to try and restore functionality/stability?

For example some components (e.g. cosmic-settings, cosmic-comp, etc.) I see that I am running a commit that is just a couple days old. If I suspect these might be the source of the issue, I would like to roll it back to a prior, verified commit.

Anyone know how to do this?

Thanks!!

If you still have older package versions in /var/cache/apt/archives/, you could run sudo apt install package-name=version.number~here to downgrade them. Otherwise, you'd need to clone the git repo for the individual component, check out the commit you want to downgrade to, and build (with sudo apt build-dep component-name followed by dpkg-buildpackage -b -uc -us), then install the resulting .deb package(s).
