Unsolved GNU/Debian update from sources fails due to GPG public key problem

nikobit

While performing common procedure apt update && sudo apt upgrade this keeps get listed among other Warning messages: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY 124F149833EAAB8E - though I defenitely have one according to apt-key list as it is stated: /etc/apt/trusted.gpg.d/vivaldi.gpg pub rsa4096 2023-01-10 [SC] [ valid till: 2025-02-28] 3360 18F2 63FA 0000 65CE D7C6 124F 1498 33EA AB8E uid [ unknown ] Vivaldi Package Composer KEY09 <[email protected]>
How to get rid of this annoying message first of all?
Please guide me as search results are definetely non relevant to my GNU/Debian stable release!

@nikobit show your /etc/apt/sources.list.d/vivaldi.list
Mine at Debian 12:

cat /etc/apt/sources.list.d/vivaldi.list 
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
deb [arch=amd64] https://repo.vivaldi.com/stable/deb/ stable main

And update key:

sudo su
apt clean
wget -qO- https://repo.vivaldi.com/stable/linux_signing_key.pub | apt-key add -
apt update

@DoctorG
First box is mirroring mine on Debian11.
After attemting the second one I got the same result:

# apt update
...

@nikobit Use the correct repo
deb https://repo.vivaldi.com/stable/deb/ stable main

@DoctorG
How to use it if

cat /etc/apt/sources.list.d/vivaldi.list

gives same output:

deb [arch=amd64] https://repo.vivaldi.com/stable/deb/ stable main

?
Looks like bug in last Vivaldi upgrade found ain't it right?

@nikobit said in GNU/Debian update from sources fails due to GPG public key problem:

https://repo.vivaldi.com/archive/deb stable Release.gpg

Check your *.list files and remove that old entry with
https://repo.vivaldi.com/archive/deb stable

There is nothing to comment out:

$ cat /etc/apt/sources.list.d/vivaldi.list 
### THIS FILE IS AUTOMATICALLY CONFIGURED ###
# You may comment out this entry, but any other modifications may be lost.
deb [arch=amd64] https://repo.vivaldi.com/stable/deb/ stable main

or, wait there are both files inside /etc/apt/sources.list.d
vivaldi-archive.list AND vivaldi.list
have no idea how it got there!

becm

@nikobit in 99% of cases (contemporary keys are provided by installed Vivaldi packages) it's

an (ancient) manually configured alternative sources.list file with
a signed-by entry referencing an explicit
alternate keyring file with outdated content.

Please check the output of

grep -nr signed-by /etc/apt/sources.list*

and take according steps (like delete the conflicting entry, parameter, etc.).

@nikobit Sorry, but i checked the debian package from Vivaldi 5.8 and after install the vivaldi.list always had as content
deb [arch=amd64] https://repo.vivaldi.com/stable/deb/ stable main

I do not know where you pcked up the wrong entry.

nikobit

well it took me an effort to locate and comment out old vivaldi-archive.list in a folder /etc/apt/sources.list.d/!
Thank a lot for a hint!
Now everything is back as it should be.
