Setting up libapt-pkg4.12 (0.8.16~exp12ubuntu6~upgrader1) ...

dpkg: dependency problems prevent configuration of release-upgrader-libapt-pkg-dev:

  Package zlib1g-dev is not installed.

Could you add the output of the following command from the disk?

cat /media/cdrom/.disk/info

Thanks in advance.

09:47 <slangasek> so I can confirm that release-upgrader-libapt-pkg-dev is on
                  the alternate CD

[Steve Langasek (vorlon)]

Confirmed that release-upgrader-libapt-pkg-dev is in the pool on the alternate CD, when it really shouldn't be. zlib1g-dev apparently isn't on the CD (it has no other reason to be there), which means the upgrade will fail when the network is unavailable.

For 12.04.1 we want to exclude release-upgrader-libapt-pkg-dev from the dist-upgrader pool on the CD, and in the meantime the release notes should advice users to wait for 12.04.1 for networkless 10.04->12.04 CD upgrades.

[Steve Langasek (vorlon)]

needs to be fixed in debian-cd, not in update-manager.

[Steve Langasek (vorlon)]

debian-cd fixed to pull release-upgrader-python-apt and not release-upgrader-libapt-pkg-dev.

[Steve Langasek (vorlon)]

Release note added:
 * Upgrades from Ubuntu 10.04 LTS to 12.04 LTS do not work using the alternate CD or the server CD as a package repository. It is recommended that users running Ubuntu 10.04 LTS wait for the 12.04.1 LTS point release, scheduled for July, before upgrading. (Bug:988941)

[DEXTER (mydexterid)]

It is not so "Precise" to say wait for the 12.04.1 with the upgrade.
The Precise server upgrade wiki also says:"It is generally recommended that users of Ubuntu 10.04 LTS wait until the first point release, due in July, before upgrading. "
Although it is only true if one would upgrade using the CDs. If the upgrade is done through the network I don't see why should one wait for .1

So please fix the wiki, and the notes, that network upgrade is OK.

[Colin Watson (cjwatson)]

It's OK for you to try it, but we aren't going to encourage it because
in our experience the extra testing from early-adopter upgraders before
.1 is important in making sure that upgrades are really solid for
everyone by the time we turn it on by default.

[Jan van Emous (jan-vanemous)]

july is nearly gone.
is there a date for the lts 12.04.1 release in the foreseeable future?
