First ,copy files in /var/cache/apt/archives ( don't copy partial folder and lock file) to your home folder , create folder ( example master deb
) and paste to it
I always this method to install update to all my machine ,with certain condition:
-open source driver in use, example if one your machine used proprietary NVIDIA driver but another one using intel, you must remove nvidia package first.
-same desktop environment. Cinnamon , kde , mate have different specific file.
- if you are using different DE, you can run update manager and compare file in update manager to master deb folder , remove file which not listed in update manager list. ( this is vey annoying to me
Than , use synaptic package manager . click file>add downloaded package , point it to master deb folder.
