Sometimes it's necessary to see what's inside a package which was not installed. Normally I use apt-file for this purpose. At most times this works fine, but in some cases I can't retrieve any information about the package contents using apt-file, meanwhile such a package have some files inside and seems not to be a meta package.

For example: Ubuntu 16.04 lts amd64, package name: linux-image-4.15.0-1010-oracle.

If I download it, using apt-get download and then extract, I can see vmlinuz-4.15.0-1010-oracle file inside of it.

But apt-file show linux-image-4.15.0-1010-oracle shows nothing.

apt-file update was made before any usage of apt-file.

So how should I use apt-file to see content information for this package? And why it shows me nothing?


You can also use dpkg -L packagename.

It is similar to apt-file, but it is only searching and listing installed packages.

Also you have to know that commands with apt means, for example: apt-get means installing packages from the INTERNET. Maybe some of your packages are not installed from the internet...
