Trouble updating - GPG error? NO_PUBKEY? Err InRelease?

[Gandolf_1]

/etc/apt/sources.list contains
deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi
# Uncomment line below then 'apt-get update' to enable 'apt-get source'
#deb-src http://archive.raspbian.org/raspbian/ stretch main contrib non-free rpi

/etc/apt/sources.list.d is empty

raspberry pi stretch doesn't appear to have the MONOIDE.


Anything else I can try??

Hi,
i installed the last release of raspbian strech lite
Raspbian-stretch-lite 2018-03-13-r
since March month i try without success to update my raspberrypi with sudo apt-get update
now i have a key error to update the rapsberry pi with command "sudo apt-get update"

I have already done this command without success
wget https://archive.raspbian.org/raspbian.public.key -O - | sudo apt-key add -

i don't know what to do for this error

Code: Select all

sudo apt-get update

Thanks for advance for any help to solve this error.

Hi,
I had a very similar problem, and this helped me:

Code: Select all

wget https://archive.raspbian.org/raspbian.public.key -O - | sudo apt-key add -
wget https://archive.raspberrypi.org/debian/raspberrypi.gpg.key -O - | sudo apt-key add -

The first command can also be found at https://www.raspbian.org/RaspbianRepository, but as you said you have already tried that. But maybe along that line, you could try something like

Code: Select all

wget https://dl.bintray.com/mpmc/deb/:Release.gpg -O - | sudo apt-key add -

which may be the key to the specific repository you need.
I hope this helps.

I have the following (standard?) addresses in my lists:

$ cat /etc/apt/sources.list
deb http://mirrordirector.raspbian.org/raspbian/ jessie main contrib non-free rpi
$ cat /etc/apt/sources.list.d/raspi.list
deb http://archive.raspberrypi.org/debian/ jessie main ui

To them correspond the keys:

$ sudo apt-key list | egrep ^pub
pub 2048R/90FDDD2E 2012-04-01
pub 2048R/7FA3303E 2012-06-17

The time stamps strike me as old.
However, if I delete them and run:

$ wget http://mirrordirector.raspbian.org/raspbian.public.key -O - | sudo apt-key add -
$ wget http://archive.raspbian.org/raspbian.public.key -O - | sudo apt-key add -

I get them back. This is the setup with which I fail to update.
The following command doesn't add a key:

$ wget https://archive.raspberrypi.org/debian/ ... pi.gpg.key -O - | sudo apt-key add -

I thought I found the reason for my problems: the switch from jessie to stretch, but no, no help:
/> cat /etc/apt/sources.list /etc/apt/sources.list.d/raspi.list
deb http://mirrordirector.raspbian.org/raspbian/ stretch main contrib non-free rpi
deb http://archive.raspberrypi.org/debian/ stretch main ui
/> sudo apt update
Get:1 http://archive.raspberrypi.org stretch InRelease [25.3 kB]
Get:2 http://mirrordirector.raspbian.org stretch InRelease [15.0 kB]
Ign http://archive.raspberrypi.org stretch InRelease
E: GPG error: http://archive.raspberrypi.org stretch InRelease: Clearsigned file isn't valid, got 'NODATA' (does the network require authentication?)

Reboot helped.

Hi,

For thoose who get the same error I used to manage it in adding dirmngr package

Code: Select all

  apt-get install dirmngr

and add manually the missing keys

Code: Select all

sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys YOUR_KEY_HERE

Hope this can help.

The fix I found was from the Repository users: Why am I getting GPG errors from a packagecloud.io repository? section in https://blog.packagecloud.io/eng/2018/1 ... migration/. The command I executed was:
