Environment
- EDR Server: 7.6.0
Symptoms
After upgrading to EDR 7.6.0, the cbupgrade tool fails with the error "The cb-enterprise postgresql10 dependencies are required for this upgrade."
Cause
The 'yum update cb-enterprise' installed postgresql13 properly, but removed postgresql10.

#baseurl=https://yum.distro.carbonblack.io/enterprise/stable/$releasever/$basearch baseurl=https://yum.distro.carbonblack.io/enterprise/7.5.2-1/$releasever/$basearch2) Run yum:
yum clean all yum install postgresql10 postgresql10-libs postgresql10-server3) Run cbupgrade:
/usr/share/cb/cbupgrade4) Once cbupgrade completes successfully, remove the added baseurl and uncomment the stable line in /etc/yum.repo.d/CarbonBlack.repo.
baseurl=https://yum.distro.carbonblack.io/enterprise/stable/$releasever/$basearch5) Also after cbupgrade completes successfully, remove postgres10 packages.
yum remove postgresql10 postgresql10-libs postgresql10-server
