Certbot installation fails on CentOS 7 due to broken dependencies

Turbocapitalist · 07-13-2019, 12:04 AM

I'm looking at CentOS 7 and see that certbot is in the EPEL repository. However, when I go to install it, the installation fails because it is insisting on specific, outdated versions of several packages. Here is one:

Code:

Error: Package: policycoreutils-python-2.5-17.1.el7.x86_64 (base)
           Requires: policycoreutils = 2.5-17.1.el7
           Installed: policycoreutils-2.5-22.el7.x86_64 (@base)

I have not used CentOS or its predecessors very much over the decades due to this kind of thing. What is the best and/or easiest way to resolve the dependency conflict?

Try installing the older version of the utilities by specifying the package name in yum https://linoxide.com/linux-how-to/in...rhel-centos-7/ it might install along side the new or you might have to uninstall the newer and install the older version

The old versions are rejected by the system, for example:

Code:

# yum install policycoreutils-2.5-17.1.el7
...
Package matching policycoreutils-2.5-17.1.el7.x86_64 already installed. Checking for update.
Nothing to do


# yum list policycoreutils
...
Installed Packages
policycoreutils.x86_64                     2.5-22.el7                      @base

So I'm not seeing a way to install the old versions side-by-side with the old ones.

Except that there are other packages present which depend on the newer versions. Time for an APT-based distro?

Just to confirm: you’re getting the error in the OP when you ran

Code:

yum install certbot python2-certbot-apache

as root?
Can you tell which package is throwing the error?

Turbocapitalist · 07-13-2019, 11:04 PM

Yes, as root.

Code:

# whoami 
root

# yum install certbot

Get in contact with the author of the package, it seems the one in epel is for an older version of RHEL/CentOS 7, for which there have been 6 point-updates already (so the current one is 7.6 and does have minor version updates in its packages from the original release).

So certbot is throwing the error...what happens with

Code:

yum install python2-certbot-apache

??

Turbocapitalist · 07-14-2019, 12:00 AM

More or less the same happens when running "yum install python2-certbot-apache"

Code:

Error: Package: policycoreutils-python-2.5-17.1.el7.x86_64 (base)
           Requires: policycoreutils = 2.5-17.1.el7

OK
Then see #6 or maybe compile from source...sorry I can’t help more.
