[Yum-devel] Problems with dependencies

[Jason Cox]

Thanks for the email.
As it turns out I have already started down the path of using tht updateinfo.xml to solve the issue.

I believe that I have worked out the format but am wonde anring if there is a good primmer on the format andthe tag usage?
Thanks

Yes, this is std. behaviour. Basically yum sees that the requirements
aren't met and so then does an "upgrade" on the package, as being on the
non-latest version is seldom the desired behaviour it chooses the latest
version.

If you install the yum-security plugin and use update-minimal, that has
behaviour that is similar to what you want (but I'm far from sure that
it will do what you want for your case, given the indirection, unless
you add the requirement to the updateinfo).

You can also use something which specifies the entire transaction, with
all the versions you want ... like "load-transaction",
"yum-debug-restore" or even using "yum shell" directly.
You can also use things like "yum-versionlock" to remove new versions
from consideration.

By far the easiest to deal with on the client side though is to control
the repos. that the client sees ... so that the latest version of what
the client sees is the version you want installed.
