Could not download all repository indexes (for Stretch)

[z0rk]

Distributor ID: Debian
Description: Debian GNU/Linux 9.0 (stretch)
Release: 9.0
Codename: stretch

Gnome Version 3.22.2

I've installed Stretch from scratch to a new laptop. After install when I check Reload in Synaptic I get the following:


Could not download all repository indexes

The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

I've tried to manually import the GPG keys as follows, but failed:

gpg --keyserver pgpkeys.mit.edu --recv-key CBF8D6FD518E17E1
gpg -a --export CBF8D6FD518E17E1 | sudo apt-key add -

Thanks for the link... but no dice.

1) Tried first option; import fails

2) Tried second option; import succeeds, but Reload in Synaptic (or apt-get update) generates same error message as mentioned in my first post

I really don't understand why I am getting these error after a FRESH install (NOT upgrade from Jessie) of Stretch?

Thanks

Same problem here. In my case, dirmngr did not get installed. Installed it and it gpg error was gone.
