When attempting installation, I get this error:
Dependency is not satisfiable: libstdc++6 required, but 4.9 is to be installed. I find this cryptic, especially since version 4.8 of this is installed, so version 4.9 should work?

Yeah 4.9 should work it's a C++ runtime library.

I think when a dependency is not satisfiable it's no longer used because it is old or not supported under 17.3 anymore.

To check on which version of libstdc is install run this:

-:::-OR look in Synaptic to see what version is installed.-:::-

Once you know what version is installed, upgrade your 17.3 and reboot. Upgrading the os will upgrade pkg's that are old thus upgrading libstdc to the current I'd think.

If that fails than the only other thing you could try if you want; is to perform a fresh install of Linux Mint 18:-

Why not try Chromium?

4.8 is installed, per synaptic.
I just wanted to see what iridium was like. I'm using vivaldi most of the time lately.
Perhaps in time I'll try 18. Have to set aside time, etc. Maybe after I receive my new external drive, and get everything backed up.

If it's not to much hassle remove 4.8 and install 4.9:-

I've never tried Vivaldi. How's it run?

If you just want to try Iridium just install a Virtual Machine and give it a spin. That way you'll have a peek while your waiting for your external to arrive. Performing backups are not on my preferred list. lol

I think you will like LM 18. Here's a review.

I've been messing around with these Chromium-based browsers for years.

Generally speaking, you will find this error appearing as newer versions of the browser are released, since they're compiled under successively newer versions of the glibc. And even if you upgrade the libstdc++ dependency, the very next error you'll get in the terminal will be that it wants a newer version of the glibc itself.

This is not something that's easy to do. A given release of any particular distro is usually built around a specific version of the glibc; almost everything will call upon it at some point or another. To upgrade that usually entails virtually rebuilding your distro from the ground up. And that's a major undertaking.....even for the experts.

Curiously, Google themselves (who sponsor the Chromium project - which is where all of these browsers get their source code), when they create Chrome, re-compile it against a very much older version of the glibc.....to ensure it's available to the largest possible user base. They recognise that not everyone is going to be running the very latest, up-to-date, cutting-edge distro.....with all the newest kernels, dependencies & libs.

I concur with Ztcoracat. Try it in a VM, if you're that interested. TBH, with all the Chromium-based browsers, with the exception of cosmetic differences (especially so with Vivaldi..!), once you've seen one, you've seen 'em all.
