I’m not disagreeing with anything you’ve said?
I’m saying that just adding Mozilla’s PPA to your sources won’t change apt’s behavior when installing Firefox unless you tell apt to prefer the package offered by the Mozilla PPA.
As someone who uses Kubuntu as a daily driver, I’m well aware of the snap drama and have worked around it using the method I pasted above.
Even though it’s an underhanded move by Cannonical, I’m still glad the OS is open source since it makes the workaround so trivial.
If you want to fully wipe the disks of any data to start with, you can use a tool like
dd
to zero the disks. First you need to figure out what your dive is enumerated as, then you wipe it like so:sudo dd if=/dev/zero of=/dev/sdX
From there, you need to decide if you’re going to use them individually or as a pool.
