I managed to play through Lemmingshades and everything is solvable except for "Unable" in the Pink rank. At least it appears unsolvable to me, due to maybe one of the skills provided being the wrong type. I can see it potentially being solvable if another miner was provided, or if the terrain at the start was probably set up better. I'm not going to attach my replays for the pack at this time. Quite a difficult pack for sure though!

The list of unsolvable levels has accordingly been updated in the OP and I can reproduce the list here:

Packs With Unsolvable Levels:

LemFanLems I - Brutal 18 and Chaos 3
Lemmings Obliterated - "The Top Card"
Lemmingshades - "Unable" (?) in the Pink rank   

It's possible to get Lix via Flatpak.

I recommend a native install over using Flatpak. You should either download Windows Lix normally or get Lix for Linux via your normal package manager. The Flatpak Lix is outdated: It's only Lix 0.10.30 instead of the current Lix 0.10.32. Reason: On Github, the D toolchain for Flatpak is outdated, the builds for Flatpak happen with a 4-year-old D compiler, which is too old.

But! If you use Flatpak, you should know where your Lix directories are. Or, if somebody else uses Flatpak, I should know where he has his directories, for helping and troubleshooting.

Flatpak on Linux:

ReadOnly:	~/.local/share/flatpak/app/com.lixgame.Lix/x86_64/stable/ someHexChecksum/files/share/lix/levels/
Writeable:	~/.var/app/com.lixgame.Lix/data/lix/replays/

Flatpak on Windows:
I don't know, nobody has used it there yet.

Here's some better versions of :geek:

Both have bolder glasses than the original. geek2.png gives the lenses a blue tint (inspired by Velma from Scooby Doo).

I stand by my original versions of :shrug:, both animated and non-animated.
