This works but its not what I was expecting to do. What I was trying to do was automatically build 'my-app' and 'app-configs' (via Jenkins) every day and upload those .deb files to Artifactory in a single repo. At some point in time (about once a week), I would want to release 'my-app' and update its control file to use a specified version of 'app-configs' (probably not the latest), then I would use a script to install this version of 'my-app', which would only require the specific version of app-configs. If I understand what you say, only 1 version of app-configs should be available in the debian repo in order for this to work. If that's the case, then what are my options? Does each daily build of 'my-app' and 'app-configs' go into a separate repository? I do find it strange that I was able to use apt-get install app-configs=1.0.5~aaa but I cannot specificy something similar through a control file. > You may have to 'hold' app-configs after that, because apt-get upgrade > will 'see' the newer version and may want to remove my-app again (I'm not > absolutely sure about this, as I'm tracking Testing so I always use > dist-upgrade - which definitely will remove my-app). > > Regards, > Frank > > > *) I'm ignoring 'priority pinning' here, as we're talking about a single > repository > I'm actually quite curious about this, as I was anticipating coping the 'released' my-app and app-configs into a separate repository for 'safer' keeping. Thanks again for an advice you can provide. Sijis
