Bug 1667135

+++ This bug was initially created as a clone of Bug #1646424 +++

python2-boto3 has dependencies issues. It requires version of rpm, which is missing:

---> Package python2-boto3.noarch 0:1.4.6-1.el7 will be installed
--> Processing Dependency: python2-s3transfer >= 0.1.10 for package: python2-boto3-1.4.6-1.el7.noarch
Package python2-s3transfer is obsoleted by python-s3transfer, but obsoleting package does not provide for requirements
--> Finished Dependency Resolution
Error: Package: python2-boto3-1.4.6-1.el7.noarch (epel)
           Requires: python2-s3transfer >= 0.1.10

               python2-s3transfer = 0.1.10-1.el7

We are affected by this too.

I bet this bug affects many people.
Any progress on this?

For anyone affected but wanting to quickly bypass issue, using "yum install --setopt=obsoletes=0 ..." like here https://www.getpagespeed.com/troubleshooting/quick-fix-for-installing-python2-certbot-dns-route53-python2-boto3-in-centos-7 works.

But that's just a temporary fix for "yum install", the "yum update" is still going to have dependency issue.

the problem is still there on our patched latest CentOS7 VMs;

Please advise as the only thing we can do right now is to;
yum update -y --skip-broken
yum install --setopt=obsoletes=0 certbot-dns-route53

It seems there was a bug fixed for 7.5, which unfortunately though created this issue, see bug 1576985

The breakdown is this:

python2-boto3 has an explicit requirement on python2-s3transfer, not python-s3transfer.

The epel7 package of s3transfer creates a binary rpm called python2-s3transfer, which also provides the virtual name python-s3transfer.

The rhel7 package of s3transfer creates a binary rpm called python-s3transfer, which obsoletes EPEL's python2-s3transfer, but it doesn't provide the python2-s3transfer name, that python2-boto3 explicitly depends on, thus the transaction is failing.

Will need to do some testing, possibly through a COPR repo to verify the transaction issue.

Adding needinfo on the maintainer to chime in.

I'll clone this bug in order to provide a workaround for boto3, to basically require python-s3transfer instead of python2-s3transfer. That should fix the dependency issue for now.
