I have a server running on Debian Wheezy.
It's apt source file has following configuration:
deb http://ftp.uk.debian.org/debian/ wheezy main non-free contrib
deb-src http://ftp.uk.debian.org/debian/ wheezy main non-free contrib
deb http://security.debian.org/ wheezy/updates main contrib non-free
deb-src http://security.debian.org/ wheezy/updates main contrib non-free
# wheezy-updates, previously known as 'volatile'
deb http://ftp.uk.debian.org/debian/ wheezy-updates main contrib non-free
deb-src http://ftp.uk.debian.org/debian/ wheezy-updates main contrib non-free
When I try to update I get GPG errors for official Debian repositories:
root@osgb:~# apt-get clean
root@osgb:~# apt-get update
Get:1 http://security.debian.org wheezy/updates Release.gpg
Get:2 http://ftp.uk.debian.org wheezy Release.gpg
Get:3 http://ftp.uk.debian.org wheezy-updates Release.gpg
Get:4 http://security.debian.org wheezy/updates Release
Ign http://security.debian.org wheezy/updates Release
E: GPG error: http://security.debian.org wheezy/updates Release: The following signatures were invalid: NODATA 1 NODATA 2
If I remove security repository from sources.listfile and try to apt-get update again, then same error this time pops for ftp.uk.debian.org
root@osgb:~# apt-get clean
root@osgb:~# apt-get update
Get:1 http://ftp.uk.debian.org wheezy Release.gpg
Get:2 http://ftp.uk.debian.org wheezy-updates Release.gpg
Get:3 http://ftp.uk.debian.org wheezy Release
Ign http://ftp.uk.debian.org wheezy Release
E: GPG error: http://ftp.uk.debian.org wheezy Release: The following signatures were invalid: NODATA 1 NODATA 2
What I tried so far, is;
- Tried a number of other mirrors,
- Tried to install
debian-keyringanddebian-archive-keyringdeb files manually, - Removed
/var/lib/apt/listsand forced regeneration by creating the partial folder, apt-get cleaning etc. (As offered in a number of posts)
None of them helped.
So, what is this error about, ie what does it mean? And do you have any idea to solve it?
UPDATE (18/08/2015):
Server doesnt have any disk space problem. It has a single partition setup which has plenty of empty space:
root@osgb:~# df -h
Filesystem Size Used Avail Use% Mounted on
rootfs 259G 22G 224G 9% /
udev 10M 0 10M 0% /dev
tmpfs 1.2G 240K 1.2G 1% /run

UPDATE (20/08/2015)
As suggested, I tried updating the keys however it seems that my server already has the latest keys. And unfortunately mighty NODATA error persists.

Resolution and final words:
I thought it cannot be a firewall issue since the port used is 80 and I can connect manually. However, the firewall was detected to be blocking server's request in the application level. Firewall thought apt-get is a suspicious application to be blocked unless allowed explicitly. We added it to the whitelist and it is up and ok now!
