Network Upgrade for Ubuntu Server (8.04 -> 8.10)
Continuing my series on how to upgrade to Ubuntu 8.10 “Intrepid” I now bring you steps on how to upgrade your Ubuntu Server installation. Again, these steps are nearly as simple as a desktop upgrade. The Ubuntu development team has done a really great job of making upgrading simple and painless.
First of all you’ll need to install the upgrade management utility:
sudo aptitude install update-manager-core
Once that is installed (it may already be there, YMMV), start the upgrade manager:
sudo do-release-upgrade
Simply follow the on-screen instructions at this point. Note: The upgrade manager will alert you that upgrading via remote ssh connection is not suggested, however I have done it multiple times without issue. Again, your milage may vary.
Enjoy
It may be a good idea to suggest the use of ‘screen’ when doing major updates over ssh. It would (hopefully) avoid leaving a system in a partially-upgraded state in the case of network outages (whether due to software or other.
Thanks for your tutorial.
Please note that your aptitude command is missing a dash. Should be:
sudo aptitude install update-manager-core
you missed one point :
Edit /etc/update-manager/release-upgrades and set:
Prompt=normal
To the author, thanks for having this information available.
Jimmy and Aikiko: Thank you for your comments! Now it works properly!
(I don’t know why but the 8.10 iso for ubuntu-server-i386 just won’t install properly on my Dell Optiplex GX240. Something about passwd depends and libc6. I even verified the written CD had the right md5sum.)
Thanks.
Thanks Aikiko for the comment
