Ubuntu Upgrade

[dan]

Hi
I'm running Ubuntu 8.10 on my server, and Canonical have deprecated support for it, so apt-get no longer works properly. I'm contemplating upgrading it to 10.04.1 LTS, but I'm just acutely aware that DA might break since it's a binary rather than relying on something like Python, Perl, etc.
My question is - will I have issues if I upgrade? I'll be upgrading with do-release-upgrade on the command line, so everything will be updated via apt. This will obviously also update, during the process, key binaries - exim, apache, etc..
I also have to update it 3 or 4 times to get to the version I want. It wants to run an upgrade path 8.10 -> 9.04 -> 9.10 -> 10.04.1.
Feedback appreciated.

Note that I'm responding only to one small part of your post:

Maybe.

I'll be upgrading with do-release-upgrade on the command line, so everything will be updated via apt. This will obviously also update, during the process, key binaries - exim, apache, etc..
You'll definitely have problems if apt-get updates exim, apache, etc.[/quote]
Many programs in the hosting stack shouldn't be updated by apt-get, but rather by DirectAdmin using CustomApache or CustomBuild.

Check to make sure what apt-get excludes, and past the exclusions here for better information.

I also have to update it 3 or 4 times to get to the version I want. It wants to run an upgrade path 8.10 -> 9.04 -> 9.10 -> 10.04.1.
Feedback appreciated.
My recollection is that even Ubuntu people don't recommend this. I strongly recommend asking this on the Ubuntu forum.

mm. actually ubuntu suggests that you can jump versions so long as the original and target versions are LTS versions, or you can upgrade to the target version in increments, as i suggested, this is their recommended upgrade path.

however, it doesn't look like the ubuntu upgrader will be able to leave the hosting stack alone, as it's not technically apt-get that's doing the upgrade, it's some other do-release-upgrade script which handles the whole thing from start to finish.

my question now is this: if i run do-release-upgrade several times to get my server to 10.04.1 LTS, even if it has upgraded the hosting stack, would re-running customapache/custombuild after the upgrade overwrite the versions that are there with the versions that *it* wants to install?

Let's presume you're right and it won't leave the hosting stack alone. That's a serious problem. It should only update software originally installed from .deb packages. If it won't leave other software alone it's quite dangerous to use.

I doubt, though, that it really does that. Does the package management system have a system for handling excludes? Have you used it to exclude everything that should be excluded?

If ubuntu has updated packages it shouldn't, then it's unlikely that custombuild will fix the problem; it leaves too much alone to account for customizations.

I strongly suggest you ask the question of DirectAdmin Support (http://www.directadmin.com/support.html).

hmm. well, i'm in the process of backing up all the user's home directories and mysql databases, /usr/loca/directadmin, etc.
suppose the upgrader does upgrade all the hosting stack. would it be possible to apt-get remove all the relevant packages and have custombuild re-install them?

for the first stage of the upgrade, this is what do-release-upgrade said it was going to do:

i don't see anything significant in there, but then again, i don't know exactly what it is i'm looking for. the only thing i can see that would have anything to do with the hosting stack is the apache2.2-common upgrade which i don't see as being an issue as it's currently running apache 2.2.10.

i've just send this same message to da tech support too to get their view on it. will post back when i hear something.

Maybe this could help you. http://www.linuxforums.org/forum/debian-linux/53089-how-exclude-some-packages-during-apt-get-upgrade.html. You could work out excluded packages with DA support. I can't help you with this, because we use CentOS and yum, which excludes packages by default.

[nobaloney]

Great find, Tom.

The packages that need to be excluded from upgrade (and most from installation) can probably be found in these forums searching for yum exclude, but then of course the package names will probably need to be adjusted for Debian/Ubuntu.

Jeff

[tomtom901]

Yum example:



# PUT YOUR REPOS HERE OR IN separate files named file.repo
# in /etc/yum.repos.d
exclude=apache* httpd* mod_* mysql* MySQL* da_* *ftp* exim* sendmail* php* bind-chroot*

awesome. although, i think i may leave the o/s upgrade, and upgrade the entire server in 12 months. using custombuild right now to get all the hosting stack up to date, i'll just live with that for now, and install 11.04 LTS next year on a new server.

thanks anyway.
