Hello guys,

hope everything is going good today.

I'm trying to renew our SSL Certificate in our Zimbra Single-Server ( Release 8.8.15.GA.3869.UBUNTU18.64 UBUNTU18_64 FOSS edition, Patch 8.8.15_P36 ).
Unfortunately the installation is failing due to the following error:

zimbra@mail:~$ /opt/zimbra/bin/zmcertmgr deploycrt comm /var/tmp/cert/server.crt /var/tmp/cert/ca_bundle.crt
** Verifying '/var/tmp/cert/server.crt' against '/opt/zimbra/ssl/zimbra/commercial/commercial.key'

Caused by: java.lang.ClassNotFoundException: com.zimbra.cert.MyPKCS12Import

This is what I tried so far:
- Run the certificate installation command with zimbra services on and with zimbra services off (except for ldap, it seems to be always required).
- Verified the chain with commands "/opt/zimbra/bin/zmcertmgr verifycrtchain /var/tmp/cert/ca_bundle.crt /var/tmp/cert/server.crt" and with commands "/opt/zimbra/bin/zmcertmgr verifycrt comm /opt/zimbra/ssl/zimbra/commercial.key /var/tmp/cert/server.crt /var/tmp/cert/ca_bundle.cr"
- Run "chown -R zimbra:zimbra /opt/zimbra" and "/opt/zimbra/libexec/zmfixperms".

Do you have any suggestion?

Thank you a lot in advance.

Best regards,
Michael
