Symptoms
BA upgrade could fail due to inability to upgrade the libcurl721 rpm to version >= 7.37
The upgrade fails with the following error in a log:
Error: Package: curl721-7.21.7-5.el6.x86_64 (@pa-central-repo)
Requires: libcurl721 = 7.21.7-5.el6
Removing: libcurl721-7.21.7-5.el6.x86_64 (@pa-central-repo)
libcurl721 = 7.21.7-5.el6
Updated By: libcurl721-7.37.0-13.el6.x86_64 (pa-central-repo)
libcurl721 = 7.37.0-13.el6
Cause
Earlier, Odin provided two rpms: libcurl721 and curl721 of version 7.21. The curl721 package stricly requires libcurl721 of the same version.
Later, curl721 was dropped from the "pa-central-repo" yum repository, and version of libcurl721 was bumped.
As a result, an attempt to upgrade BA fails on inability to upgrade the libcurl721 package.
Resolution
Remove the curl721 rpm from the affected host:
rpm -e curl721
