Description of problem: Paramiko cannot be installed on CentOS 7.2.1511 with vault.centos.org repos. In 7.2.1511 python-pyasn1 doesn't provide python2-pyasn1, which required by python-paramiko. Version-Release number of selected component (if applicable): python-paramiko-2.1.1-0.4.el7 How reproducible: Always Steps to Reproduce: 1. Change yum repos to vault.centos.org: sed -e "s/#baseurl=/baseurl=/g" -e "s/mirrorlist=/#mirrorlist=/g" \ -e "s;mirror.centos.org/centos;vault.centos.org;g" \ -i /etc/yum.repos.d/CentOS-* 2. Freeze yum repos to 7.2.1511 echo 7.2.1511 > /etc/yum/vars/releasever 3. Install python-paramiko yum install python-paramiko Actual results: Error: Package: python-paramiko-2.1.1-0.4.el7.noarch (epel) Requires: python2-pyasn1 You could try using --skip-broken to work around the problem You could try running: rpm -Va --nofiles --nodigest Expected results: python-paramiko successfully installed Additional info: Introduced by https://bugzilla.redhat.com/show_bug.cgi?id=1559133 I think, that python-paramiko should depends on python-pyasn1, not python2-pyasn1.
It's probably easiest to work around this by creating a local dummy python2-pyasn1 package that requires python-pyasn1. There's a bunch of these in EPEL already (see https://fedoraproject.org/wiki/User:Tibbs/EPELPythonStubPackages) but this case is a little different as python2-pyasn1 does actually exist in the current EL-7 release that EPEL targets, which is why I'd suggest doing this locally. I'm very reluctant to change the python-paramiko package in EPEL7 as it's supposed to be the same as the one in RHEL 7.4 apart from the release tag.
Sorry, old versions of EL not supported.
