I just tried to sign a new version of my AddOn (still experimental, so not publicly viewable), and it failed with the message:
Update available 7.8.0 → 7.9.0
Run npm i -g web-ext to update
However, this is not that easy in my case. I’m a Linux user, and I’ve installed web-ext via my package manager. So I can’t just update web-ext directly without creating conflicts on next package update.
Although Arch Linux usually is fast in providing updates, we’re approaching holiday season and the package maintainer might be on vacation.
So I need away to use the existing web-ext, and honestly I don’t understand why there isn’t some grace time in general.
