Gem dine data og lave en frisk installation af versionen du ønsker
(Feisty), men det er næppe det du (man) umiddelbart forstår ved at
opgradere?. I følge vejledningen på
http://www.ubuntu.com/getubuntu/upgrading er det en dårlig idé (kan
ikke lade sig gøre) at springe opgraderinger fra én version til den
næstkommende over, og det anbefales desuden at opgraderingen sker via
(d)et grafisk(e) interface og via nettet. På
https://help.ubuntu.com/community/UpgradeNotes står der:

"Skipping versions is not advised and can cause a lot of damage to
your installation. If you are using an earlier version, and want to
'skip' a version, the only safe way is to backup your data and do a
fresh install, or to progressively upgrade to each successive version.
An example of this would be if your are running 6.06 (Dapper) and want
to upgrade to 7.04 (Feisty). You would have to first upgrade to 6.10
(Edgy), and then again to 7.04 (Feisty) or simply do a clean/fresh
install of 7.04 (Feisty). An easy way to test a newer version of
Ubuntu on your machine for compatibility is trying the Desktop CD
(Live CD) before upgrading."

På samme side er der "upgrading information" for de for tiden
understøttede versioner.

I noten for 6.10 > 7.07 som findes i det første link ovenfor står:

"Before you start

   *      You can only directly upgrade to Ubuntu 7.04 ("Feisty
Fawn") from Ubuntu 6.10 ("Edgy Eft") (see UpgradeNotes)
   *      Be sure that you have all updates applied to Ubuntu 6.10
before you upgrade
   *      The latest version of Update Manager (0.45.2) must be
installed before you upgrade. Otherwise, you will receive an
Authentication failed error. See here for instructions how to check if
you have the required version.

Note: If you have a version of Ubuntu which was released before Ubuntu
6.10, please see Installation/UpgradeFromOldVersion for information on
how to upgrade."

Her (der) https://help.ubuntu.com/community/Installation/UpgradeFromOldVersion
stå:

"Installation/UpgradeFromOldVersion

This document provides notes on upgrading to Ubuntu 7.04 (Feisty Fawn)
from a version of Ubuntu released before Ubuntu 6.10 (Edgy Eft)." og

"Clean install with /home on separate partition

If your /home directory is contained on a separate hard-disk partition
you should be able to upgrade by performing a clean install of Ubuntu
7.04/Feisty and 'adopting' the old /home directory." hvorefter det
nærmere er forklaret hvordan det gøres på en sikker måde.

Vær særlig opmærksom på
https://help.ubuntu.com/community/FeistyUpgradesManual for

"Manual command-line upgrade (not recommended)

Please note - this method is less reliable. If you use this method,
you MUST be prepared to fix problems manually, such as packages being
unexpectedly removed, apt crashing unexpectedly, etc. Using Update
Manager (see above) is likely to be much less problematic.

Instructions for this method can be found on FeistyUpgradesManual."
