Hello everyone,
I am having some issues installing this application onto Trisquel (aramo).
I followed the instillation steps as listed but am receiving the following error. I apologize if there is any mistake on my end:

usr@computer:~/git/apt-transport-i2phttp$ ls
debian  LICENSE  main.go  Makefile  README.md  release.sh
usr@computer:~/git/apt-transport-i2phttp$ sudo apt install build-essential i2pd

build-essential is already the newest version (12.9ubuntu3).
i2pd is already the newest version (2.53.1-1jammy1).

Thank you so much for all of your time and energy. Any support you can help provide is immensely appreciated.
