Debian instructions subtly wrong

[jkominek]

The line

echo deb [signed-by=/usr/local/share/keyrings/edgedb-keyring.gpg]\

isn't right. The [ and ] need to be escaped, or the whole thing quoted, or something. Maybe there's some shell it'll work with, but for the bourne shells, it'll be turned into any of the one-character filenames whose names match one of the characters in "signed-by=/usr/local/share/keyrings/edgedb-keyring.gpg", if you have one. Otherwise it will fail.
