Debian bookworm can't install git

Hello, I'm hoping someone can help me. I can't install git on Debian 12 bookworm. I've been installing offline and then updating. I've tried editing the source list in Nano and synaptic, tried a fresh image, changing from Rufus to Unetbootin. nothing seems o work. any help is greatly appreciated!

sudo apt-get install git

Package git is not available, but is referred to by another package.
This may mean that the package is missing, has been obsoleted, or
is only available from another source

E: Package 'git' has no installation candidate

 

I'm pretty sure if you install without an internet connection, the apt sources will not be set up correctly if you connect to the internet later. That means it is unable to get packages.

share the output of this command 

Yeah that's makes sense, but I'm not sure how to edit it.

cat /etc/apt/sources.list
# deb cdrom:[Debian GNU/Linux 12 _Bookworm_ - Official Snapshot amd64 LIVE/INSTALL Binary 20231016-21:54]/ bookworm contrib main non-free non-free-firmware

Yes, I used sudo apt get with the same results. the package manager repository is using some .io domains. nit sure if that matters

This is what I see in the package manager repository. but it doesn't match the sources.list. even after editing the sources.list I still the errors and some new ones.

deb packagecloud.io/rodw-au/rodw-au/debian/ bookworm main

deb-src packagecloud.io/rodw-au/rodw-au/debian/ bookworm main

deb www.linuxcnc.org/ bookworm 2.9-uspace

deb repository.qtpyvcp.com/apt/ develop main

deb cdrom:[Debian GNU/Linux 12 _Bookworm_ - Official Snapshot amd64 LIVE/INSTALL Binary 20231016-21:54]/ bookworm non-free-firmware non-free main contrib

I definitely tried Sudo apt update. Maybe a better option is to install buster and upgrade it to bookworm instead. Could this be a root issue?

Despite what Tommy thinks, you do need to have internet connection when running the installer. Otherwise, apt is set up to only get programs from your CD which you probably don't have. This is your issue.
edit your file as follows
replace the contents with:


then type

Our installer follows best practice and adds all of the third party repositories (including linuxcnc) in other folders under the /etc/apt/ folder.
sources.list only contains the debian defaults which are set dynamically by the installer.[
