Make yum not installing dependancies if main package failed

  • 772

I have 3 packages corepkg, corepkg-optB and corepkg-optC. corepkg-optC depends on corepkg-optB, corepkg-optB depends on corepkg. I've created a repo of these 3 packages. When I run yum install corepkg-optC, and corepkg failed, yum installs corepkg-optB and corepkg-optC. It is not what I would like.

I would like corepkg-optB failing if corepkg is failed and corepkg-optC failing if corepkg-optB failed because corepkg failed.

My specfile looks like this:

Name: corepkg
Version: 1.0.0

%pretrans
if ! grep -q foo /etc/hosts
then
    exit 1
fi

%package optB
Requires: corepkg = 1.0.0

%package optC
Requires: codepkg-optB = 1.0.0

I tried Requires then Requires(pre), but give me the same result:

# yum install corepkg-optC
error: %pretrans(corepkg-1.0.0-1.el7.noarch) scriptlet failed, exit status 1
Error in PRETRANS scriptlet in rpm package corepkg-1.0.0-1.el7.noarch

  Verifying  : corepkg-1.0.0-1.el7.noarch                                          3/3

Installed:
  corepkg-optC.noarch 0:1.0.0-1.el7.noarch

Dependency Installed:
  corepkg-optB.noarch 0:1.0.0-1.el7.noarch

Failed:
  corepkg.noarch 0:1.0.0-1.el7.noarch

I tried Requires(pretrans) but it was a non-sense as everything is a single yum transaction.

All corepkg are mine, I can modify specfiles. Any idea? Thank you!

EDIT: package B and C are not dep but more like additionnal stuff to corepkg. It is similar to packages php-* or python-*. Similar because my packages corepkg-optB and corepkg-optC are modules (text files) and means nothing without corepkg. I'm saying that because some php-* packages work standalone.

yum rpm specfile

  1. Looks like there is no simple answer on your question. I find question similar to yours. And looks like this is only one way, you should check in %pre section properly installed packages, but not using rpm command. May be check for existing files or something like that.
