I've tried installing the latest QGIS relaease on my Ubuntu according to the installation guide on the website (which has worked before).
wget -qO - https://qgis.org/downloads/qgis-2021.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
I got this error code:
gpg: key 46B5721DBBD2996A: 1 signature not checked due to a missing key
gpg: key 46B5721DBBD2996A: "QGIS Archive Automatic Signing Key (2021) <qgis-developer@lists.osgeo.org>" not changed
gpg: Total number processed: 1
gpg: unchanged: 1
When trying to install now, using:
sudo add-apt-repository "deb https://qgis.org/ubuntu $(lsb_release -c -s) main"
I get:
N: Skipping acquisition of configured file 'main/binary-i386/Packages', as repository 'https://qgis.org/ubuntu focal InRelease' doesn't support architecture 'i386'
N: Skipping acquisition of configured file 'universe/binary-i386/Packages', as repository 'http://miktex.org/download/ubuntu bionic InRelease' doesn't support architecture 'i386'
W: GPG error: http://packages.cloud.google.com/apt cloud-sdk InRelease: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY FEEA9169307EA071 NO_PUBKEY 8B57C5C2836F4BEB
E: The repository 'http://packages.cloud.google.com/apt cloud-sdk InRelease' is not signed.
N: Updating from such a repository can't be done securely, and is therefore disabled by default.
N: See apt-secure(8) manpage for repository creation and user configuration details.
Doesn anyone have an idea what I could do? I tried deleting the old keys in sources.list, but it isn't working...
