EDR: Cbupgrade Aborted Due to Missing Postrgresql10

Products

• Carbon Black EDR (formerly Cb Response)

Issue/Introduction

After upgrading to EDR 7.6.0, the cbupgrade tool fails with the error "The cb-enterprise postgresql10 dependencies are required for this upgrade."

Environment

• EDR Server: 7.6.0

Cause

The 'yum update cb-enterprise' installed postgresql13 properly, but removed postgresql10.
 

Resolution

Perform the following steps on the Primary EDR server. These steps are not needed on minions in clustered environments. 

1) Modify /etc/yum.repo.d/CarbonBlack.repo based on the EDR version you upgraded from in the table in Additional Notes.  Comment out the stable line and add the baseurl like below:

#baseurl=https://yum.distro.carbonblack.io/enterprise/stable/$releasever/$basearch
baseurl=https://yum.distro.carbonblack.io/enterprise/7.5.2-1/$releasever/$basearch

2) Run yum:

yum clean all
yum install postgresql10 postgresql10-libs postgresql10-server

3) Run cbupgrade:

/usr/share/cb/cbupgrade

4) 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/$releasever/$basearch

5) Also after cbupgrade completes successfully,  remove postgres10 packages.

yum remove postgresql10 postgresql10-libs postgresql10-server
