5.8.4 to 5.8.5 upgrade error

[J.A.K]

When trying the upgrade from 5.8.4 to 5.8.5 the upgrade fails with an error of:

Checking group memberships...
usermod: group 'nagcmd' does not exist

Not sure if something broke when the OS was updated from RHEL 8.3 to 8.4, but is there any fixes I should do to correct this outside just creating the group?

Hello @J.A.K,

Thanks for reaching out and want to get the upgrade.log so we can see what is going on, but also check to see if 'selinux' got re-enabled. Sounds like the os was upgraded and the Nagios XI environment as well so we have several variables to look at.

Code: Select all

sestatus

Your nagcmd in /etc/group should look like this:

Code: Select all

grep -E 'nagcmd' /etc/group

nagcmd1001:nagios,apache,snmptt

Please send us the following:

Code: Select all

tree -pufidg /usr/local/nagios/ > /tmp/treeresults.txt && tree -pufidg /usr/local/nagiosxi/ >> /tmp/treeresults.txt

Code: Select all

cat /etc/*release
uname -a

The upgrade log is located: '/usr/local/nagiosxi/tmp/upgrade.log', please send this along as well.

Thanks,
Perry

In order:

[g9988725@vml1038 ~]$ sestatus
SELinux status: disabled

[g9988725@vml1038 ~]$ grep -E 'nagcmd' /etc/group
#nagcmd56017:nagios,apache,snmptt

Looks like the line is commented out? Pulling the entirety of /etc/group I see this line right above it:

nagios56017:nagios,apache,snmptt
#nagcmd56017:nagios,apache,snmptt

tree isn't installed on my system.

For the update log it appears to be blank:

Hello @J.A.K,

Thanks for following up with the details.

Since the upgrade log did not even get written to, the upgrade did not get very far.

A couple of things, please check to see if noexec on /tmp?

Code: Select all

mount | grep -E 'noexec'

Then re-run the upgrade:

Code: Select all

./upgrade -n 2>&1 | tee /tmp/nagiosxi/upgrade.log

Thanks,
Perry

Looks like I should be good. After you pointed out to verify the group exists (I really should have checked that to begin with honestly) and I saw it was commented out I just incremented the group ID one not to conflict with the Nagios group and uncommented. After that the upgrade ran without issues.

I'll have to do some checking on my end to see what happened there, but I think this can be closed out. Thank you for pointing me in the right direction!
