I installed the following packages:
agda/stable 2.5.4.1-3 all
agda-bin/stable 2.5.4.1-3+b1 amd64
agda-mode/stable 2.5.4.1-3 all
agda-stdlib/stable,now 0.17-1 all
agda-stdlib-doc/stable 0.17-1 all

I followed the instructions at <https://agda.readthedocs.io/en/v2.6.2/getting-started/hello-world.html>.

The file <hello.agda> checked correctly within Emacs, but when I tried to compile the file <hello-world.agda> I received the following output:

$ agda --compile hello-world.agda

A brief web search led me to believe that this was a problem with the Debian package and I uninstalled the packages listed above and installed Agda with cabal instead, which produces the expected output.
