Hi!
Similar to this question: https://forums.ni.com/t5/NI-Package-Manager-NIPM/Linux-NI-device-drivers/td-p/4096945
I am working on Ubuntu 20.04 LTS and installed ni-ubuntu2004firstlook-drivers-stream.deb from this download page (version 21.5). Following the installation manual, i executed apt update afterwards. This was the result:
sudo apt update

E: The repository 'https://download.ni.com/ni-linux-desktop/stream/deb/ni/focal focal Release' does not have a Release file.
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.
Is the SSL certificate expired?
Additionally i tried updating with SSL verification disabled, which showed the following error:
sudo apt -o "Acquire::https::Verify-Peer=false" update

E: Some index files failed to download. They have been ignored, or old ones used instead.
What could be the issue?
