installing QGIS on Ubuntu 20.04

  • 772

I installed QGIS on Ubuntu 20.04, and it doesn't really work. I used the advice from the QGIS website.

On the terminal, I have a problem with the QGIS key and keystrings. When entering these commands:

wget -qO - https://qgis.org/downloads/qgis-2020.gpg.key | sudo gpg --no-default-keyring --keyring gnupg-ring:/etc/apt/trusted.gpg.d/qgis-archive.gpg --import
sudo chmod a+r /etc/apt/trusted.gpg.d/qgis-archive.gpg

the system tells me:

neisolsayaparizabi@neisolsayaparizabi-N2x0WU:~$ wget -qO - https://qgis.org/downloads/qgis-2020.gpg.key | sudo gpg --no-default-keyring --keyring gnupg-ring:/etc/apt/trusted.gpg.d/qgis-archive.gpg --import
gpg: key F7E06F06199EF2F2: 1 Beglaubigung wegen fehlendem Schlüssel nicht geprüft
gpg: Schlüssel F7E06F06199EF2F2: "QGIS Archive Automatic Signing Key (2020) <[email protected]>" nicht geändert
gpg: Anzahl insgesamt bearbeiteter Schlüssel: 1
gpg:              unverändert: 1

You can see that my system is in German.

It means something like:

key F7E06F06199EF2F2: 1 authentication not verified because of missing key.

When looking at the list of authentifications, the key in question is there:

What can be the problem?

QGIS is installed, but when wanting to connect to a map server, it indicates that this is not possible due to an error in the SSL protocol.

How can I resolve this? I tried to ask the question on the QGIS forum but somehow didn't get admitted.

ssl certificates qgis

  1. On my system it says:

    gpg: keyring '/etc/apt/trusted.gpg.d/qgis-archive.gpg' created
gpg: key F7E06F06199EF2F2: 1 signature not checked due to a missing key
gpg: key F7E06F06199EF2F2: public key "QGIS Archive Automatic Signing Key (2020) <[email protected]>" imported
gpg: Total number processed: 1
gpg:               imported: 1
gpg: no ultimately trusted keys found

    But with the following lines in my /etc/apt/sources.list:

    deb [arch=amd64] https://qgis.org/ubuntu focal main # disabled on upgrade to focal
deb-src https://qgis.org/ubuntu focal main # disabled on upgrade to focal

    QGIS installs fine using sudo apt install qgis giving version 3.14.1
