apt update error

[soniabu]

Hi everyone, I hope you are all well. I'm fine.
I've been encountering this error for about a week now when trying to update my Booworm system.
Can anyone suggest me how to find a solution?
thank you so much

Try:

Code: Select all

apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E88979FB9B30ACF2

Then:

Code: Select all

apt-get update

excellent advice Trap, everything was resolved even if I didn't compress everything that happened.
1000 thanks

Hi Sonia, although the suggestion from Trapster works, you'll probably still get a warning about apt-key deprecation (btw, no big deal , just a warning)
(EDIT: hmm. looking at your screenshot better now, there's no warning so it's OK then)

Official way these days to add the google repo key is: (is without the use of apt-key)
wget -q -O - https://dl.google.com/linux/linux_signing_key.pub | tee /etc/apt/trusted.gpg.d/google.asc >/dev/null
see: https://www.google.com/linuxrepositories/

About the other thing (non-free etc...):
Change in /etc/apt/sources.list non-free to: non-free non-free-firmware (in fact add non-free-firmware)
for example, becomes: deb http://deb.debian.org/debian bookworm main contrib non-free non-free-firmware
And do apt update
These are recent changes (from sometime ago already though), so on your (older) install it must be fixed.

OH! Hello great Fred. I made the changes you suggested and these are the results I got.
I haven't upgraded yet because I wanted to submit these images to you before I get into any trouble.
If you give me ok I'll go ahead with the upgrade.
Sorry for the inconvenience but I feel like such a little donkey and so I proceed with caution.

I feel like such a little donkey

Exactly like that I feel too
Well... seriously, I can't really advice, doesn't seem doing harm to upgrade all, but perhaps fine too if you only upgrade firefox-esr apt install firefox-esr, up to you.

well Fred: update all.
thx a lots Fred, sonia
