Problem with removing rpm package

Question

I'm trying to install one package on CentOS 6.7

yum install varnish

but I'm getting that I have a package which doesn't belongs there (is for CentOS 7)

---> Package varnish.x86_64 0:4.1.0-1.el7 will be installed

which creates problems during installation. Trying to update to correct one package

rpm --nosignature -U --oldpackage https://repo.varnish-cache.org/redhat/varnish-4.1.el6.rpm

returns package varnish-release-4.1-2.el6.noarch is already installed

Running rpm -qa | grep varnish gives varnish-release-4.1-2.el6.noarch so how can I remove package for CentOS 7 when is not listed there so I can install correct varnish version?

yum --showduplicates search varnish

returns

varnish-docs-2.1.5-5.el6.x86_64 : Documentation files for varnish varnish-libs-2.1.5-5.el6.i686 : Libraries for varnish varnish-libs-2.1.5-5.el6.x86_64 : Libraries for varnish varnish-libs-devel-2.1.5-5.el6.i686 : Development files for varnish-libs varnish-libs-devel-2.1.5-5.el6.x86_64 : Development files for varnish-libs varnish-2.1.5-5.el6.x86_64 : High-performance HTTP accelerator

still nothing related to varnish.x86_64 0:4.1.0-1.el7

Answer 1

OK, i have founded varnish 4.1.0-1.el7 in /var/cache/yum/x86_64/6/epel/. Strange. Have removed that folder and reloaded correct package - all went back to normal state.

Answer 2

Try

rpm -qa | grep varnish | xargs rpm -e

to remove every varnish package installed.

Answer 3

Looking at the rpms in the repository it seems that rpm varnish-release-4.1-2.el6.noarch.rpm just contains an entry for yum to use. Try removing

/etc/yum.repos.d/varnish-4.1.repo

and any other versions in that directory and start again.
