Description of my issue

Hello! I am trying to migrate to yunohost 4.* but i cannot manage to do it. It seems like I have some GPG keys verification problem, but I am not sure how to solve it. Here is the log of the migration https://paste.yunohost.org/raw/nobavudute

I know there’s a similar post on the forum but I can’t understand French at all, I’m sorry.

Thanks in advance!

Wokay, not sure to understand how you ended up loosing the signature keys for both repos … But let’s try this:

wget -O- https://forge.yunohost.org/yunohost.asc -q | apt-key add -qq - >/dev/null 2>&1
wget -O- https://archive.raspberrypi.org/debian/raspberrypi.gpg.key -q | apt-key add -qq - >/dev/null 2>&1

Hello!
The migration process started, it worked!
I really don’t know how I lost those two keys :sweat_smile:
Thanks a lot!

p.s. A small note: I had to run wget and apt-key add separately
