Can you post here your /etc/apt/sources.list.d/passbolt.sources content ? Do you have any other file in /etc/apt/sources.list.d folder ?
Can you share full output of your apt update ?
Are you using Ubuntu 20.04 or 18.04 (cat /etc/os-release) ?
I guess Ubuntu 18.04 is not able to read well new apt list format.
You can try to delete passbolt.sources file:
sudo rm /etc/apt/sources.list.d/passbolt.sources
and create a /etc/apt/sources.list.d/passbolt.list with this content:
deb [signed-by=/usr/share/keyrings/passbolt-repository.gpg] https://download.passbolt.com/ce/ubuntu focal stable
We provide only Ubuntu 20.04 package repository and our package has not been tested on Ubuntu 18.04 so run it at your own risk.
Usually, it is a bad idea to mix Ubuntu 20.04 focal packages with Ubuntu 18.04 packages.
I was able to reproduce your issue, can you check rights of /usr/share/keyrings/passbolt-repository.gpg ?
It must be 644:
$ sudo stat -c %a /usr/share/keyrings/passbolt-repository.gpg
644
$ sudo stat -c %A /usr/share/keyrings/passbolt-repository.gpg
-rw-r--r--
And be owned by root:
$ sudo stat -c %U:%G /usr/share/keyrings/passbolt-repository.gpg
root:root
Some other checks:
$ file /usr/share/keyrings/passbolt-repository.gpg
