1.1.2. Installation from source

produces the following on a fresh 22.04

ubuntu@ip-172-31-34-232:~$ sudo apt-get --no-install-recommends -y install \
    build-essential pkg-config erlang \
    libicu-dev libmozjs185-dev

E: Unable to locate package libmozjs185-dev

This is similar to 1316 which states libmozjs185 is now packaged.

For running from source, you need one of the listed spidermonkey libs from the section above.
In Ubuntu Jammy you could install libmozjs-91-dev or libmozjs-78-dev to get this working.

Since you are trying to build CouchDB from source, the section with the dependencies gives you information, what you need to install. The apt command or later the make script will tell you, whats eventually missing.
