  • apt-get is the package manager for Debian/Ubuntu system and their derivatives. You are using RedHat, therefore should be using yum instead.

  • Now are you on Debian or on Redhat? Have you tried to use yum instead of apt-get?

The default package manager on Red Hat Linux is yum, not apt-get. Even though one of the error messages you posted mentions Debian/Ubuntu, I'll assume you're using a Red Hat system like your question suggests. You can probably confirm your Linux distro by using one of the following commands:

cat /etc/*-release
lsb_release -a
cat /proc/version

There is a Plone documentation page for Preparing to install Plone with notes for CentOS, which is essentially a free variant of Red Hat. That page suggests the following yum install command for dependencies for Plone 5:

yum install gcc-c++ patch openssl-devel libjpeg-devel libxslt-devel readline-devel make which python-devel wv poppler-utils

Or for dependencies of Plone 4:

yum install gcc-c++ patch openssl-devel libjpeg-devel libxslt-devel readline-devel make which python-devel

There are, of course, caveats for whether or not you're using the system default version of Python, so you'll want to check that out. You should also make sure that you're looking at the correct documentation for the version of Plone that you're trying to install.

Once you've installed the dependencies, then you would run the installer as you tried to do previously, assuming the arguments are correct:

sudo ./install.sh --target=/home/admin/Plone --build-python zeo

  • I don't know why the Plone documentation would provide a one-liner command that doesn't get all the dependencies... Use this to install the libz development files: yum install zlib-devel

  • You say that you're "using python 2.7", but this doesn't make sense since your command is trying to build Python, not use an existing installation. Does "no result" mean that nothing was installed? Or zlib-devel was installed, but python still does not build? If you're using new commands and getting new errors, you should post what you did and the error message you're getting. You might also want to answer the following: 1) what OS and version are you running; 2) what version of Plone are you trying to install?
