我正在运行 Ubuntu 15.10。
我的/usr/share/applications/sublime_text.desktop包含以下内容：
[Desktop Entry]
Version=1.0
Type=Application
Name=Sublime Text
GenericName=Text Editor
Comment=Sophisticated text editor for code, markup and prose
Exec=/opt/sublime_text/sublime_text %F
Terminal=false
MimeType=text/plain;
Icon=sublime-text
Categories=TextEditor;Development;
StartupNotify=true
Actions=Window;Document;
[Desktop Action Window]
Name=New Window
Exec=/opt/sublime_text/sublime_text -n
OnlyShowIn=Unity;
[Desktop Action Document]
Name=New File
Exec=/opt/sublime_text/sublime_text --command new_file
OnlyShowIn=Unity;
当我右键单击xxx.mdGnome 文件（以前称为“Nautilus”）中的降价文件 ( ) 时，即使我选择了“查看所有应用程序”，也看不到“Sublime Text”作为选项。
我甚至尝试添加%F到线Exec=/opt/sublime_text/sublime_text -n和Exec=/opt/sublime_text/sublime_text --command new_file在[Desktop Action Window]和[Desktop Action Document]分别，但它并没有改变任何东西。
我什至跑了sudo update-desktop-database。
我究竟做错了什么？
当我运行时dpkg --list 'linux-image*'，输出显示我只4.10.0-37安装了：
Desired=Unknown/Install/Remove/Purge/Hold

但是，当我显示 的内容时/boot，还有其他旧内核：
