• production (production servers)

Populate apt.mycompany.com

# apt-get install \
   --download-only \
   escenic-content-engine-6.3 \
   escenic-sse-proxy-1.0
# reprepro \
    --keepunreferencedfiles \
    -Vb /var/www/html/apt.mycompany.com \
    --component non-free \
    includedeb \
    development \
    /var/cache/apt/archives/escenic-content-engine-6.3_6.3.0-11_all.deb

On pres1.staging.mycompany.com, put in its /etc/apt/sources.list.d/escenic.list

deb https://user:pass@apt.mycompany.com staging main non-free

Promote a package from staging to production

MyCompany QA has verified version 6.3.0-11 on staging and want to roll this out in production:

    --component non-free \
    includedeb \
    production \
    /var/cache/apt/archives/escenic-content-engine-6.3_6.3.0-11_all.deb
