Thanks Timothy (and Tom too for your earlier reply).

Great, your instructions were exactly what I needed! I had googled around and came across these instructions at for a manual install to address a similar version situation a few years ago, but yours are more detailed and well explained, so I'm going to try that.

Speaking of Linux Mint vs. Ubuntu vs. package versions, since I've recently been delving into all this (yeah, a quarantine project ...): I happen to have seen that Ubuntu 20.04 LTS is due out literally any day now (23 Apr 2020), and I learnt that Linux Mint typically has their update based on that in 2 months, i.e., end-June 2020. But there seems no evidence that that will contain a more recent version of ddrescue (how would one find out?) as I assume the software repositories run in parallel and are not specifically tied to a particular OS release.

So what is not clear to me, not just for the gddrescue package but really for any third-party software package: - Which version of software gets incorporated into a particular release (LTS or not) of Linux? Or, as I speculated above, are the software repository updates really independent (in their timelines) of the OS updates?
- Who decides this and based on what?
- What is the minimal regression testing that needs to happen to "certify" a new version of a package gets the green light, and who does this? The software developer (António in this case) if he wants to see his updated versions get more widespread use? Anyone? No one?

I looked around some more and came across MOTU, the package maintainers' group, which I guess partially answers some of my questions above. So how does one contact the ddrescue "person" in MOTU to encourage him or her to update it?

Just getting my feet wet (again) with how Linux ecosystems currently work after being away from Unix for more time than I'd care to admit, so sorry if these questions seem somewhat basic.

Wow, this is pretty remarkable. I wonder if the package maintainer can
be contacted to get this ironed out. By the way, Linux Mint and Ubuntu
share the same packages, so the software repository for Linux Mint is
actually the same one as Ubuntu and there are no differences. Note
that Linux Mint 19.3 is based on Ubuntu 18.04 LTS. Until a new LTS
comes out (20.04), Linux Mint will continue to be based on Ubuntu
18.04 LTS. ...
