In T256877 we 've identified that the nodejs images that zotero uses rely on packages that have been installed from stretch-backports. That has been by design and has worked well up to now, but stretch-backports is being retired as stretch moves from oldstable to LTS.
Relevant parts of zotero's blubber.yaml are pasted below for easier reference
version: v4 base: docker-registry.wikimedia.org/nodejs10-slim:0.0.1 variants: build: base: docker-registry.wikimedia.org/nodejs10-devel:0.0.1
We can probably just bump to using https://dockerregistry.toolforge.org/buster-nodejs10-slim/tags/ and https://dockerregistry.toolforge.org/buster-nodejs10-devel/tags/ respectively and solve the issue easily. Assuming that passes npm test we should be able to upgrade with ease.
