Hello Lorran,
bem-vindo to the Glufke Forum!
Then you should be able to query the log in "/u01/app/oracle/product/11.2.0/xe/config/log", as the error message instructs you.
You will probably come across any specific error message, which will allow you more focused searches, or will allow the person to help you with more efficiently.
well .. You could consult this link, where a forista describes an installation error in Ubuntu:
http://www.vivaolinux.com.br/topico/Ora ... buntu-1204
This link highlights two other links, which may help you solve your problem:
http://ubuntuserverguide.com/2012/06/ho ... 12-04.html http://docs.oracle.com/cd/E27300_01/E27 ... oting.html
in the first link mentioned above, the moderator alert That Ubuntu libraries may be missing to allow the correct installation of Oracle.
I recommend that instead of following exactly what this linked link proposes, that you first open the file mentioned in your error message and check exactly the error that must be registered there.
This will avoid that you waste time following instructions that can not even be related to your error.
Please, if you have more details of your error and still can not solve the same, post these details here in Glufke so that forists are able to help you.
A big hug!
