Random CI failures

[anders-kiaer]

Sometimes CI fail already at install step, with:

npm ERR! cb() never called!npm ERR! This is an error with npm itself. Please report this error at:
npm ERR!     <https://npm.community>npm ERR! A complete log of this run can be found in:
npm ERR!     /home/runner/.npm/_logs/2021-05-25T09_03_04_478Z-debug.log
Error: Process completed with exit code 1.

Searching for npm issues, most sources suggest either clearing cache (not relevant for CI?), setting node/npm constraints and/or update npm to latest version. Pinning down what is the direct cause in our case requires more feedback, e.g. see the .log?

Haven't seen this in a long time. Might have been fixed by GitHub themselves.
