Use some of the following tips to help you get packages installed onto a
system without working Internet.

Grab APT download links
-----------------------
To get a list of the links for DEB files to install all that you will 
need (hopefully) to get a package running, do something similar to the 
following in a terminal:

    sudo apt -qq --print-uris install wine | cut -d\' -f 2 > urls.txt

This will create a file called "urls.txt" in the current directory with
all of the links of DEB files needed to install WINE. The contents of
this file will look something like this:

http://deb.debian.org/debian/pool/main/libs/libstb/libstb0_0.0%7egit20200713.b42009b%2bds-1_amd64.deb
http://deb.debian.org/debian/pool/main/f/faudio/libfaudio0_21.02-1_amd64.deb
http://deb.debian.org/debian/pool/main/v/vkd3d/libvkd3d1_1.1-5_amd64.deb
http://deb.debian.org/debian/pool/main/w/wine/libwine_5.0.3-3_amd64.deb
http://deb.debian.org/debian/pool/main/w/wine/wine64_5.0.3-3_amd64.deb
http://deb.debian.org/debian/pool/main/w/wine/wine_5.0.3-3_all.deb

This way, you can easily download these packages on another computer if
the current one does not have Internet access but was able to run 
'sudo apt update' at least once. WGET can be ran from a list of URLs
like so:

    wget -i urls.txt
    
You would then 'cd' into the directory with these packages and run:

    dpkg -i *.deb
    
    ...to install all of the packages.

apt-offline Method
------------------
You can also grab EVERYTHING from your APT-friendly distribution's
repositories so that you never need to use the Internet to install
software ever again, like so... Though, you will need a large hard
drive for this.

1. You will need to download the 'apt-offline' package on the computer
   with working Internet and install it to both computers. For example,
   if you are using a Debian-based (Bullseye) distro, you would look
   here: https://packages.debian.org/bullseye/apt-offline

2. On the computer without Internet, run the following in a terminal:
    
    sudo apt-offline set ~/my.sig
    
3. Copy the "~/my.sig" file to a USB hard drive and moun that hard drive
   to the computer with working Internet.
   
4. On the computer with working Internet, run the following in a 
   terminal:
   
    sudo apt-offline install "/path/to/downloaded/packages/folder"
    
    ...the "/path/to/..." part is where all of the DEBs are going to
    go.
