OneAgent installation has failed. Installer returned error code: 1

[vishnu_kumar]

Hi All,

Am getting this error when upgrading Oneagents of the 1.281 versions.

OneAgent installation has failed.
Installer returned error code: 1 If the problem persists, please contact support .

There is no documentation on what this error means.
We retried the upgrade post oneagent restart, still same error.

Has anyone faced this error?

Hi @vishnu_kumar 

• You can try updating to the most stable version.
• Share the support archive with Dynatrace support team for further investigation and sooner resolution.
• Uninstall the current version, remove all related previous version files according to the OS  Linux or   Win

Check the related troubleshooting reference:

Hello Vishnu,

You can either collect the 'OneAgent Diagnostics' from GUI or from command mode.

GUI - Go to host settings and you can find it over there. Hope, your server is still communicating to Dynatrace.

Command Line - https://docs.dynatrace.com/docs/shortlink/oneagentctl#create-support-archive

Once collected, please share the logs to Dynatrace support team for further investigation.

Hi @vishnu_kumar 

You can also follow the provided approach by @Sajarra as an alternative method for collecting logs either to download it locally, or share it with Dynatrace for further analysis.

KR,

Thanks Everyone for the replies, I used "uninstall" script in the agent files and launched the update.

Worked like charm
