When updating an endpoint Linux or macOS agent via the RSA NetWitness Endpoint user interface, the error message below is displayed after selecting the package.
The file properties are not shown, because the file does not meet the requirement.
This condition is a result of the file permissions on the agent package. Local administrators have full control of the file. Local Users have Read & Execute and Read permissions. Even if the RSA NetWitness Endpoint user is member of the domain admins group, the effective permissions will be the same for local user account.
This Issue has been resolved in RSA NetWitness Endpoint 188.8.131.52.
There are two workarounds for the issue:
Add the Endpoint User to the local administrators group
As a local administrator, check the "write box for agent package" option.
