libreplan :取决于: tomcat6，但是它不会被安装

Question

我尝试使用来自Libreplan网站和本指南的步骤在14.04服务器系统上安装Libreplan。

我可以在没有问题的情况下添加PPA，但是当我使用sudo apt-get install libreplan命令时，我会得到以下错误消息。

Reading package lists... Done

安装tomcat6会解决这个问题吗?如果是这样的话，它可以与tomcat7一起安装吗？还是这里还有一个我不知道的问题？

编辑:我没有收到来自sudo apt-get update或sudo apt-get dist-upgrade的错误消息

下面是sudo apt-get install libreplan生成的错误消息

Answer 1

是的，您可以，您应该安装包tomcat6与tomcat7一起解决您的问题。两个包都可以并行安装。

但是软件包应该是自动安装的。我怀疑你有更多的问题。

由于这个原因，运行

sudo apt-add-repository universe
sudo apt-get update
sudo apt-get install tomcat6

并将错误信息添加到您的问题中。

Answer 2

sudo apt-get install libtomcat6-java 
sudo apt-get install tomcat6

这能解决你的问题。即使已经安装了tomcat6，也可以安装tomcat7。
