On tools-sgebastion-08, we've got:
$ jq --version jq-1.5-1-a5b5cbe
Would it be possible to upgrade this to v1.6? 1.6 includes the utf8bytelength function, which is not in the currently installed version.

https://stedolan.github.io/jq/manual/v1.6/
Debian Bullseye has v.16 packaged -- https://packages.debian.org/bullseye/jq
The package would have to be backported to Stretch (-2 versions) to be available on the Toolforge bastions.
OK, thanks. If it's not an easy install, it's not that important. I've found a different way to do what I needed to do anyway.
