I have installed apt-offline on tow machine runing debian jessie pc1 (online) and pc2 (offline).I am using the following command :sudo apt-key exportall | sudo gpg --no-default-keyring --import --keyring /etc/apt/trusted.gpg to fix missing key and successfully update pc2, the problem is that the signature file can not be generated for some package like dkms . I am using the following command to get the signature file  :apt-offline set debian-install.sig --install-packages dkmsIs that possible to install a specific package like dkms and linux-headers on pc2 using the command apt-offline ?
How to install a specific package with dependencies using apt-offline command?
