What is the easiest way to "patch" an Ubuntu ISO so that the default mirror is different?


  • We're behind a proxy so upon initial installations, the process isn't able to the see the mirror
  • We do have an internal mirror I'd like to point to
  • I'm looking for something easy so that future ISOs can just be "patched" then burned

Specify the details of the mirror and/or proxy in the preseed file. All of the possible preseed values you can use should be provided in the manual for the Ubuntu version you're using, but the keys you're interested in are probably mirror/http/proxy and/or mirror/http/hostname.
