There have been a lot of users having problems with the upgrade to Intrepid. With the delay in Alpha 1, and large interest in testing, I created this howto to get new testers into Intrepid on the right foot, and hopefully cut down on the number of posts asking for help with various issues.
For those who are new to development testing, and think Intrepid may be over your heads, it probably is. However, right now there is a call for testers for the packages in the hardy-proposed repository (updates to hardy which have not yet been released, and may include bugs). This is much easier and safer, yet still very necessary, and could be a more appropriate way for you to contribute to Ubuntu. You can read about enabling the proposed repositories here and here. For the rest, who are still interested in Intrepid, please read on.
Please note the following before upgrading to Intrepid:
- Intrepid is a development release. Breakages are common and to be expected, so only use if you have the time and knowledge to deal with such breakages. It is not recommended to use Intrepid as your main OS, as serious damage may occur.
- These instructions only apply while Intrepid is in a pre-alpha state. Once the Alpha 1 iso's are released, installing by CD is the easiest and most reliable method. You can check the release schedule here.
To upgrade to Intrepid 8.10:
- Start with a fresh install of Hardy 8.04, right off the CD. Do NOT update at this point.
- Open your sources.list file for editing by running the following command in a terminal:
Code:gksudo gedit /etc/apt/sources.list
- Use the "Search">"Replace" tool to replace all references to "hardy" with "intrepid". Save and exit the file.
- Start Update Manager, hit "Check". If a window comes up asking for a "partial update" press "Cancel" to return to the main update-manager window, and then continue to the next step. NEVER do "partial upgrades" or "dist-upgrades" without checking what is being changed!
- Uncheck the "debconf" update, as it will not install properly unless another update has already been applied.
- Hit "Install Updates".
- Once this is done, start Synaptic, and carefully apply the remaining updates manually. They will appear in the "Installed (upgradeable)" category. Before installing make sure that the update will not remove any important packages, however installing other packages should be fine. If you are unsure whether a specific package should be removed, feel free ask on the forum or IRC.
- Once this is done, you can restart and you should be successfully be running Intrepid.
Some post install notes:
- If it fails to boot, it may not necessarily be your fault; as Intrepid is in heavy development, the system is not always in a bootable state. You can wait and hope a fix is release, or try to diagnose the problem. You can always check the forum to see if people are having problems similar to yours.
- Never install updates by doing a "dist-upgrade" or a partial upgrade. These tools can remove important packages if dependencies are not met, which occurs quite often in the developmental version. The better solution is to do a regular update, and then use synaptic to check what is being removed. If it is a dependency issue, just wait until all the correct packages are added to the repository.
Let me know if you see any issues or have any suggestions to make on the above. Good luck!
