rpm: postinstall script commands missing with EL 8
JanneKataja-TomTom opened this issue · 3 comments
rpm scalyr-agent-2 postinstall script attempts to enable service using commands that are no longer supported with RHEL/CentOS 8.
Please see Fedora packaging guidelines for Systemd packaging scriptlets (the OS contains a library of macros that can be used to enable services):
https://docs.fedoraproject.org/en-US/packaging-guidelines/Scriptlets/#_systemd
When running on CentOS 8:
[root@ca9cc96b4be0 /]# yum install scalyr-agent-2
Failed to set locale, defaulting to C.UTF-8

Switching the Python interpreter used by the Scalyr Agent.
The default 'python' command not found, will use python2 binary (/usr/bin/env python2) for running the agent.
The 'python2' command not found, will use python3 binary (/usr/bin/env python3) for running the agent.
The Scalyr Agent will use the python3 binary (/usr/bin/env python3).
Switched agent to python3
If you have an existing instance of scalyr-agent-2 process running, you need to restart it for this change to take an affect.
You can do that by running '/etc/init.d/scalyr-agent-2 restart' command.
Agent switched to python3.

Hi @JanneKataja-TomTom, thanks for the info and sorry for such a big delay.
We removed the service command from agent's install scripts. It also seems like the service command is not shipped by the docker image rather than the CentOS distribution itself.
About the systemd. We are planning to switch to distribution-specific releases in the nearest future and support of the systemd is one of the main priorities.
