Ukraine

I wonder if that's because they're exporting gasoline rather than making it available there.

No. Apparently a few days back, the Kremlin also banned exports.

Kremlin bans fuel exports until the end of the year as Russia’s supply is disrupted by Ukrainian drones

So I assume that they can't actually even produce enough for domestic use at this point.

EDIT: Nah, the shortages are specific to Crimea, so it's probably a logistics breakdown there. Looking back over the article:

As The Bell notes, Crimea is also facing additional challenges due to severe weather conditions near the Kerch Strait, further complicating supply lines and exacerbating the fuel deficit. This is the first time such restrictions have been imposed on fuel sales to private individuals in the region.

This was from a month back, saying that at that point, they had a 20% margin and that if there was actually a domstic shortfall, then they'd expect rationing:

On top of this, annual gasoline production in Russia exceeds domestic demand by up to 20 percent...

If the worst comes to the worst, a crisis measure would be gasoline rationing.

You'd expect nationwide rationing rather than just rationing in Crimea in that case. Has burned through their supply for export, though, or they wouldn't have cut that off.
