I'm trying to install Ubuntu Core on my Raspberry Pi 3 B+, but after I validate the network and enter my email (I have created an Ubuntu account for it), it just says error on line 13: Snap command not found.
What should I do?
Leaving my opinion about needing an Ubuntu account aside, you should do what the error says: provide the snap command.
My guess is the Snappy store is missing, so you will have to install it manually. Open up a terminal, or, if you can't because of not being logged in, you can use [CTRL] + [ALT] + [F2] in order to get to a terminal input. Ideally, you should be able to login as a local user. From there, just use apt to install snapd and you should be good to go. If you had to use the function keys to open a terminal, iirc, the DE should be on [CTRL] + [ALT] + [F7] by default, but you may test all function keys until you find it.

Try installing the snap directly and should go on, but if it doesn't think you might have to look into your bash as I had similar issue I think with angular, despite installed and everything but I'm on limit mint mate currently
