[SOLVED] change from cdrom to USB flash drive in sources.list

I realize this is a basic syntax question, but I'm running into so many problems with my new laptop, I need a break. In /etc/apt/sources.list, how do I change the first line to use a USB flash drive instead of a CD/DVD?

deb cdrom:[Devuan ...

What for? Your approach isn't useful. Delete that line(s) and you're done.

Re: [SOLVED] change from cdrom to USB flash drive in sources.list

I have no Internet connectivity (installation was done solely via the USB flash drive), so I need to install Reaktek drivers manually (I got the .deb from MX Linux: http://mxrepo.com/mx/repo/pool/main/r/rtl8821ce/). But first I need to install some things from the USB flash drive I used for installation because Devuan puked when I tried to install the .deb.

sudo dpkg -i Downloads/rtl8821ce-dkms_5.5.2.1-7~mx21+1_all.deb
(Reading database ... 190461 files and directories currently installed.)
Preparing to unpack .../rtl8821ce-dkms_5.5.2.1-7~mx21+1_all.deb ...
Unpacking rtl8821ce-dkms (5.5.2.1-7~mx21+1) over (5.5.2.1-7~mx21+1) ...
dpkg: dependency problems prevent configuration of rtl8821ce-dkms:
 rtl8821ce-dkms depends on dkms (>= 2.1.0.0); however:
  Package dkms is not installed.

dpkg: error processing package rtl8821ce-dkms (--install):
 dependency problems - leaving unconfigured
Errors were encountered while processing:
 rtl8821ce-dkms

P.S. I know how to use vi and understand the concept of comments, as I used Unix a million years ago.

Search the Debian forums, I answered this question there a while ago.

Re: [SOLVED] change from cdrom to USB flash drive in sources.list

I found an apt trick...

mount your flash-drive, I just use the kde5/plasma system to allow me to click and mount, it came up as

/media/glenn/Devuan 4.0/   (this is using chimaera amd64)

Then as root... apt-cdrom add --cdrom=(your storage-device)

apt-cdrom add --cdrom=/media/glenn/'Devuan 4.0'

this was the lookup...

root@GamesBox:~# apt-cdrom add --cdrom=/media/glenn/'Devuan 4.0'

This line was added to my /etc/apt/sources.list

deb cdrom:[Devuan GNU/Linux 4.0 chimaera amd64 - desktop 20211012]/ chimaera contrib main non-free

I got errors with 'apt update', and synaptic (gui) only shows installed packages.

I went back and re-ran the apt-cdrom add command without resetting anything and

now synaptic shows all packages. :-)

I'm glad you asked this question because I gave up trying to get the memory stick to be an post-install repo.

I hope this helps

Re: [SOLVED] change from cdrom to USB flash drive in sources.list

I finally bought a small pack of DVD-R discs and burned Devuan 4.0 on it. I was able to install the prerequisites for the Realtek driver, the Realtek driver, firmware-amd-graphics, and then the usual updates. Thanks to everyone for saving me from installing Windows.
