[Auth] accesskey = [ACCESS KEY HERE] [Network] # Proxy to use when accessing the Uptrack server, of the form # [protocol://][:port] # The proxy must support making HTTPS connections. If this is unset, # Uptrack will look for the https_proxy, HTTPS_PROXY, and http_proxy # environment variables in that order, and then finally look for a # proxy setting in the system-wide GConf database, if available. https_proxy = [Settings] # Automatically install updates at boot time. If this is set, on # reboot into the same kernel, Uptrack will re-install the same set of # updates that were present before the reboot. install_on_reboot = yes # Options configuring the Uptrack cron job. # # GUI users will get all notices via the GUI and likely want to set # the following cron options to "no". # Cron job will install updates automatically autoinstall = no # Cron job will print a message when new updates are installed. # This option is only relevant if autoinstall = yes cron_output_install = no # Cron job will print a message when new updates are available cron_output_available = no # Cron job will print a message when it encounters errors cron_output_error = no
