First suggestion would be, Check if the caption.sty file is somewhere on the system
$ locate caption.sty
If it is not installed, most probably the package is not on the basic configuration of texlive.
I used the command
$ apt-cache search caption | grep tex

Thanks for the answer! I just had a last question, How this will change for Tex Studio?
A real scandal! One of the best pizza places in Munich now serves pineapple pizza. (Yet the pizza fisica is really good and I guess @egreg might like matematica... ;-)

I just noticed this in the announcement section of the tex.stackexchange homepage. Coincidentally I had posted a scenario detailing a use-case of accessibility. I don't know if this falls outside the scope of your workshop tomorrow.
@samcarter See, sometimes a crystal ball can be pretty useful ;-) (Exit the BOB=Bayerische Oberlandbahn at Geitau and then follow the directions to Hoch)miesing, and at the fork where you could get there going left or right go right ;-)
@L.K. if it says that you just need to install it, you should just be able to update via miktex or texlive package manager. texstudio isn't involved, that's just the editor
@JosephWright Thanks. I was just confused. Usually 'events' have a time and a sign-up thing. (I don't know what the point of the sign-up thing is. Perhaps the system then prioritises alerting you. But the time is quite useful.)
@egreg Yes. And it was a nice change from all the medieval things I had been seeing other places. Although my favourite church in Bologna (where I've been staying) is Santo Stefano, parts of which also date back to that time.
