• If issue with java SSL certificates (registering an user) check that the file /etc/ssl/certs/java/cacerts contains the CA certificates of the system and it's in JKS format. Otherwise run the following workaoround:
  • sudo update-ca-certificates -f (should generate the content of the file)
  • cd /etc/ssl/certs/java && sudo mv cacerts cacerts.old && sudo keytool -importkeystore -destkeystore cacerts -deststoretype jks -srckeystore cacerts.old -srcstoretype pkcs12 (to change from pkcs12 to jks storetype, type can be checked with keytool -list -keystore cacerts | grep "Keystore type")
