It works !
If you're seeing this page via a web browser, it means you've setup Tomcat successfully. Congratulations!

Caused by: java.io.IOException: Directory '/var/lib/tomcat8/.gitbucket' could not be created

エラーのスタックトレースで上記部分を眺めての当てずっぽうですが、
Ubuntu内で tomcat ユーザーやグループに、ファイルアクセス・書き込み権限は付与しておりますでしょうか？

以下のコマンドでユーザーを作り、アドレスの書き込み権限を与えて見てください。

$ sudo useradd -M tomcat
$ sudo chmod -R tomcat:tomcat /var/lib/tomcat8/

ご回答ありがとうございます。
```
$ sudo chmod -R tomcat:tomcat /var/lib/tomcat8/
```
↓
```
$ sudo chown -R tomcat:tomcat /var/lib/tomcat8/
```
でしょうか？

[manzyun]

Oh... そうでした。申し訳ないですorz

[sprn]

ありがとうございます。
試してみたのですが、403に変わりました。

[manzyun]

403だとForbiddenですね。

となると、自分の提案したパーミッションが間違っていそうですね。申し訳ないです。

もしかするとユーザーやグループ名に `tomcat7` か `tomcat8` を指定すると行けると思います。
