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:

Hoping it helps.

Peter

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,

Peter

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

Worked like charm
