Ubuntu: Upgrading 10.04LTS -> 10.10 using custom sources



Question:

I'm trying to upgrade to 10.10 from 10.04 LTS using a custom sources.list file that points to an unofficial mirror*. The mirror does have maverick, but I get the following output when upgrading:

boatzart@somecomputer: > sudo do-release-upgrade  Checking for a new ubuntu release  Done Upgrade tool signature  Done Upgrade tool  Done downloading              extracting 'maverick.tar.gz'  authenticate 'maverick.tar.gz' against 'maverick.tar.gz.gpg'   tar: Removing leading `/' from member names    Reading cache    Checking package manager  Reading package lists...

Here is the relevant section from /var/log/dist-upgrade/main.log:

*I'm located inside of USC, and for some crazy reason any sustained downloads to anywhere outside of the University are throttled down to 5kbps inside of my lab. Because of this I need to use the following sources.list:

deb http://mirrors.usc.edu/pub/linux/distributions/ubuntu/ lucid main restricted universe multiverse  deb http://mirrors.usc.edu/pub/linux/distributions/ubuntu/ lucid-updates main restricted universe multiverse  deb http://mirrors.usc.edu/pub/linux/distributions/ubuntu/ lucid-backports main restricted universe multiverse  deb http://mirrors.usc.edu/pub/linux/distributions/ubuntu/ lucid-security main restricted universe multiverse  

I've tried adding four more entries to the sources.list with s/lucid/maverick/ but that didn't help.

Does anyone know how to fix this? Thanks!


Solution:1

I've hit this before when using a local mirror. What I recall worked for me was:

  • add and entry in /etc/hosts for us.archive.ubuntu.com with the address if you mirror
  • change /etc/apt/sources.list to point to us.archive.ubuntu.com
  • sudo apt-get update
  • sudo do-release-upgrade

at this point, apt and do-release-upgrade should think they're talking to us.a.u.c, and hopefully it will work.

this does require that mirrors.usc does not care what 'site' header is sent in the http get.


Solution:2

I managed to this quite simply by updating the sources.list file to include only the local archive url and executing the following two comands:

sudo apt-get update

sudo do-release-upgrade

Worked like a charm and 650MB of updates downloaded within minutes. The actual installation took much longer.
