Error message when uninstalling Oneagent

Shirai — Thu, 20 Feb 2020 09:56:47 GMT

An error message was displayed when uninstalling Oneagent Linux.

Confirmed that "semanage" is not installed.

Is the uninstallation successful?

If script reached it's end (it is, you see it in last line) in general everything should be uninstalled properly.

Hello Toshimasa,

The OneAgent uninstallation is indeed finished, but due to the error you see in the output, i.e. lack of semanage utility on your host, the uninstall script wasn't able to remove SELinux context for your custom-path OneAgent installation.

The last thing to complete the uninstall in this case is to install semanage utility onto your host and use it to remove OneAgent contexts manually. You can find out how to do that using semanage docs (e.g. execute man semanage on your machine).

Regards,

Bartek
