我在Amazon EC2 Ubuntu服务器中运行了基于Java的Web应用程序。我使用Jasper报告来生成一些PDF格式的报告。我使用“ Jaspersoft Studio”构建了这些报告
现在,当我尝试生成报告时,出现此错误
net.sf.jasperreports.engine.util.jrfontnotfoundexception font 'Times New Roman' is not available to the jvm
因此,我决定安装Microsoft字体。我打过
sudo apt-get install ttf-mscorefonts-installer
它根本没有用。相反,它给了我以下通知
$ sudo apt-get install ttf-mscorefonts-installer
Reading package lists... Done
Building dependency tree
Reading state information... Done
Package ttf-mscorefonts-installer is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source
E: Package 'ttf-mscorefonts-installer' has no installation candidate
我该如何解决这个问题?
更新
我的source.list
包含在下面。我可以安全编辑吗?
