Upgrade from v7.0.1 to v7.13.0

[Nils]

Hi Community,

I like to upgrade from v7.0.1 to 7.13.0.

I upgraded as mentioned in Confluence Upgrade steps.

Unfortunately I get the following error:

I checked that the MySQL Database is running and accessible.

org.apache.jasper.JasperException: Beim Verarbeiten von [errors.jsp] ist in Zeile [13] eine Ausnahme erzeugt worden

10:     <link rel="shortcut icon" href="johnson/fav-confluence.ico">
11:     <%
12:         JohnsonPageI18NProvider johnsonPageI18NProvider = (JohnsonPageI18NProvider) BootstrapUtils.getBootstrapContext().getBean("johnsonPageI18NProvider");
13:         String translations = johnsonPageI18NProvider.getTranslations().serialize();
14:     %>
15:     <script>
16:         window.i18n = <%=translations%>;

I checked the community and found an entry from @Mark Heintze

He had nearly the same problem (https://community.atlassian.com/t5/Confluence-questions/HTTP-Status-500-Internal-Server-Error/qaq-p/1657603).
I am using Ubuntu.

Has anyone an idea or approach?

Thank you :)

Regards
Nils 

EDIT: I was able to solve this.

Do you mind sharing the solution, so others could benefit? :-)

The problem was not to start the installation with sudo and to check the installation directory.
