[Qgis-user] Problem installing QGIS on Ubuntu 20.04 - key authentification

[Ben Hur Pintor]

Hi Eva,

AFAIK, the 2019 keys have recently expired thus a new one was added fairly
recently for 2020 (a few days ago if I'm not mistaken).

The error you're mentioning also happens to me when I try to download the
key from a keyserver and add the key to apt in without manual fingerprint
verification.

When I use the longer method to add the key, that is to verify the key
first and add it afterwards, the error doesn't occur on my machine.

>From the QGIS website:
*Get and verify the key*

wget -O - https://qgis.org/downloads/qgis-2020.gpg.key | gpg
--importgpg --fingerprint F7E06F06199EF2F2

pub   rsa4096 2020-08-08 [SCEA] [expires: 2021-08-08]
      3987 7635 093F 2656 0197  11FA F7E0 6F06 199E F2F2uid
[unknown] QGIS Archive Automatic Signing Key (2020)
<qgis-developer at lists.osgeo.org>


*Add key*

gpg --export --armor F7E06F06199EF2F2 | sudo gpg --no-default-keyring
--keyring gnupg-ring:/etc/apt/trusted.gpg.d/qgis-archive.gpg
--importsudo chmod a+r /etc/apt/trusted.gpg.d/qgis-archive.gpg


What I've noticed is that the *trust* of the new key is *[unknown]* instead
of *[ultimate]* which could be the cause why adding it in one command
fails. I'm not sure as well if this has any repercussions as to the
validity of the keys. Probably they still need to be signed as trusted
since they are new. P.S. I'm not an expert with GPG or keys.

Try to use the longer method for adding the keys and see if it works for
you.


All the best,
Ben Hur
