Re: [Trisquel-users] "Ubuntu LTS: Many vulnerabilities despite long-term support"

[sitereg]

Package helpers are solely used for modifying existing free-software  
packages. `ubuntu-purge` (https://devel.trisquel.info/trisquel/ubuntu-purge)  
is used for mirroring the upstream Ubuntu repository (only `main` and  
`universe` components) and also excluding software which are from these  
components but we do not want them (like chromium, or vrms, etc).

I suppose this file does the job,
