Short version of what I had to do to get the certificate working on Ubuntu:
- Concatenate the wildcard certificate file and godaddy bundle certificate into one file.
- Downloaded "Keystore Explorer 4.1.1" on a windows.
- Created a new keystore file (JKS type)
- Tools > Import Key Pair
- Select the key type (we used OpenSSL)
- Choose the key file from your previous server you performed your CSR on.
- Select the concatenated certificate file
- Enter "unifi" for the alias
- Use "aircontrolenterprise" for the key pair password when requested.
- Choose File, Save As
- Set the keystore password to "aircontrolenterprise"
- Save file as "keystore"
- Upload to /var/lib/unifi/ and replace the existing "keystore" file.
- Restart ace.jar
