Here is an old VMexample which is strange, it looks like Debian has removed this from all the repos. The easiest solution is just to upgrade to a kernel with a working/supported headers, but we don't like doing things the hard way. In this case it's a 1 year old Debian 11 install, but this can and does happen on random Linux distros sometimes, especially Debian based. apt-cache search `uname -r` linux-image-amd64 - Linux for 64-bit PCs (meta-package)........

First of all make sure contrib is enabled in /etct/apt/sources.list, if not follow this guide to add "non-free contrib" to the repos. https://realtechtalk.com/How_to_Add_Contrib_Packages_to_DebianLinuxMint_by_editing_etcaptsourceslist-2636-articles ZFS is popular because it provides actual error checking and correction to a level that is be........

Here is an example /etc/apt/sources.list after a default Debian 11 install but generally this applies to almost any Debian. # deb cdrom:[Debian GNU/Linux 11.2.0 _Bullseye_ - Official amd64 NETINST 20211218-11:12]/ bullseye main #deb cdrom:[Debian GNU/Linux 11.2.0 _Bullseye_ - Official amd64 NETINST 20211218-11:12]/ bullseye main deb http://deb.debian.org/debian/ bullseye main deb-src http://deb.debian.org/debian/ bullseye main........

We know it is deprecated but there are still systems that are running Debian 8, or at least applications that used old packages such as PHP5 that you may need an environment to stage testing/updates for it.

I doubt many people are doing this, but if you want an all Linux dev environment for Windows apps that you have made in Python, then you're probably using Wine, Python and maybe pyinstaller. The below error happened with pyinstaller and it has a lot to do with how Wine identifies paths/drives vs where you execute python.exe from Long-story short solution Never execute python commands from /root because that maps to Wine's default Z:, so any operations performed in /r........

You just add on "non-free" at the end of each repo, like the example below: If you wanted contributed packages then you could also add "non-free contrib" to each repo line. Don't forget to do an "apt update" to see the new packages, this is especially handy for getting more drivers for devices with the firmware-linux-nonfr........

These types of errors are normally caused by misconfiguration of your /etc/apt/sources.list. In this example on Debian 10, if you didn't complete the install correctly, you will have no repos enabled and only rely on CDROM. "Package wget 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 'wget' ha........
