The line left by the installer usually looks something like: 
deb cdrom:[Name of CD/DVD - The word Official and the Date]/ buster main

and if you mount either the usb or the .iso to /media/cdrom then apt can 
find it and you can continue installing pkgs from it after first boot.

Haven't people warned you that apt or apt-get is preferred over synaptic?  
Do it the easy way.

Yes, but ... <chuckle>
By default automount of flash drives is enabled and
    /media/richard/Debian testing amd64 1/debian
is how the system identifies the mounted flash drive.
[And I've forgotten how to disable automount]

Can't do that as it is already mounted. Tried another workaround and 
crashed the system. Doing a re-install now. As I've work to do, I'll 
install manually install the needed packages before closing the installer.

Opinions differ ;/

> Do it the easy way.

That's why I use Synaptic.
Besides I suspect a typical user will use a GUI when possible.
I have found a problem and believe I should document it. Besides, before 
retirement, I was an inspector. Concern for "minor" details is my nature.

Thank you.

Looking at one of my sources.list files, I wonder if it shouldn't be
	deb "file:///media/ .......
(3 slashes instead of 1) ??

My experience with automounters is that if you unmount / eject manually, 
it won't auto remount until you unplug and replug the drive. So from the 
file manager, select the mount point and from the right click menu 
select 'unmount', 'eject', 'safely remove', or whatever your file 
manager calls it, and then you should be able to mount it manually (from 
a terminal) wherever you want it.

$ sudo mount /dev/$DEVICE /media/cdrom

I believe synaptic lets you configure the sources without manually 
editing sources.list. See Settings > Repositories .

I was wondering about that. I've never had a clear understanding of when 
to use 1 slash and when to use 3. I assumed that in this case 1 was 
acceptable because how Synaptic's error message was phrased when 
attempting Edit --> Reload Package Information.

That's not so clear cut. MATE's Caja offers 2 choices ["Eject" and 
"Safely Remove Drive"]. Both remove it from MATE's Places menu. Using a 
subsequent mount command will mount it "read only". Have not checked for 
other ramifications.

I found that after I posted. Didn't have time to fully investigate. I 
didn't act as I expected. Need to pursue documentation.

Wikipedia [1] is your friend. The short version: in the three-slashes
variant, there's a little space between the two last, where you could
put a hostname (you see it now, when you squint?). If that host name
is empty, 'localhost' is assumed.

But in the case of localhost, you can leave out the two leading slashes
altogether. So file:///foo/bar and file:/foo/bar are equivalent and
both mean file://localhost/foo/bar.

Whether your strange desktop software (sorry, I couldn't resist)
implements that correctly or not is quite another story, though.

Cheers
