Problem with server upgrade

I have a problem with one offline environment. It wants to do a server upgrade and I get the problem of no permissions for the Dynatrace user to the /tmp directory.

Error: Precondition verification failed on host ‘IP’ due to: Script has returned code 0 with status OK and with details: sudo: ldap_sasl_bind_s(): Can't contact LDAP server

Dynatrace user dynatrace:dynatrace doesn't have access to following directories: /tmp - cannot access. Make sure they are accessible and permissions are granted properly.

The server was installed with the root account. Nothing has been changed on the server.

Interestingly when I manually log in to this user I can perform all operations normally. In addition, DT server itself created a directory there despite the information that it has no permissions.

Hi @radek_jasinski ,

is this error retrieved after uploading the updates bundle via Cluster Management Console in the "Settings / Automatic update" page?

Yes, the packages are already uploaded to the server.

Have a nice day!

Hi Radek, were you able to find the solution in the meanwhile? 

The only constant is change. Finding ways for great things to happen!

Hi Ana,

The problem was that the servers were added to LDAP and this caused an unintelligible error on the DT side, even though the components are running on a local user (root). After disconnecting the servers from LDAP, the update went through correctly.


Have a nice day!

@radek_jasinski looks like the issue is in badly configured operating system.
When you run sudo it gives you an error: ldap_sasl_bind_s(): Can't contact LDAP server

I think someone configured the PAM on the Linux host for LDAP and it's not working properly. I belive the installer checks prerequisites by running some commands using sudo and it checks if there is anything in the stderr output. In your case there is.

Please have someone fix the sudo and I believe it will start working again as expected.
