Re 5: repository download again - how to install offline

(Anybody investigating the Forbidden error?)

Response to https://trisquel.info/forum/re-4-repository-download-again-how-install-offline :

Your /etc/apt/trisquel.sources only has the "Optional backports repository" as a suite. "ecne" and "ecne-updates" are missing. That command adds them:
$ sudo sed -i 's/Suites:/& ecne ecne-updates/' /etc/apt/trisquel.sources

You can remove /etc/apt/sources.list since "Trisquel sources have moved to /etc/apt/sources.list.d/trisquel.sources".
