Solved: OneAgent installation failed on xxxx: Failed to elevate installer process privileges

Hello,

We have agent update problems on some hosts. We can see this on the installer logs:

When running the installer as root, no problems.

Any idea ?

Best regards,

We had an issue like this where for some reason Linux was changing our permissions. It was hard to track down and I dont quite recall what it was. But the permission level would change randomly, I almost want to say it was security app converting the permission level.

Hi @jprio ,

this could mean some capabilities where removed from a OA binary or the folder structure/ownership changed. Please run a healthcheck to pinpoint files/folders causing a problem

 # /opt/dynatrace/oneagent/agent/tools/oneagentctl --healthcheck

In case of problems the healthcheck will try and recommend a way to remediate the problem, you may see something like this:

(info): [Test Name]: File Capabilities Test
(info): [ID]: 2
(info): [Status]: FAILED
(info): [Action Item]: Reinstall the agent to amend file capabilities and check for external interference.
(info): [Reason]: File capabilties are not set correctly.

Best,

Mark
