cf https://wiki.debian.org/Firmware I think that the only firmwares installed are those you installed yourself manually (if any), no one is automatically pulled by default. as root: # aptitude search firmware would display most of the firmwares (it's a search by names containing 'firmware' and some firmwares do not contain 'firmware' in their name). The status 'ii' means a firmware is installed. What I meant previously is that it is preferable to have a firmware (related to a hardware) that is coherent with the driver for this hardware included in the kernel. So if you have a hardware that needs a firmware and you use a Backports kernel, it is probably preferable to install the Backports version of the needed firmware. > > Finally, a very important question: > > Can I go back to where I was before the update ( with only stretch > > source ) ? > > You should definitely be able to do this since the `apt upgrade` command > you > ran ended without any errors (your system is not broken anyhow). > > > I mention this because the official documentation itself (and you) > > states that you do not recommend what I did. > > > > There is a way to "I pull a rope" and go back to my sturdy/robust port > > of stretch repositories/resources ? > > Simply revert the changes sources (apt edit-sources) and > `apt update && apt upgrade` [...] I do not think this will do the trick: if I recall correctly, it will end up with Backports packages marked something like 'local' or 'obsolete' without being downgraded to their Strech version. The best solution would probably to do a fresh install. But if you want to take the chance, here is a trick to downgrade: https://wiki.debian.org/SystemDowngrade
