NO_PUBKEY DE8B853FC1555 Problem with installing Passbolt on Ubuntu 24.04.1 LTS

I used the guidance in this article (https://www.passbolt.com/docs/hosting/install/ce/ubuntu/)

I have a newly installed Ubuntu 24.04.1 LTS

During step 3 of the installation I get the error

Err:5 https://download.passbolt.com/ce/ubuntu focal InRelease
The following signatures couldn't be verified because the public key is not available: NO_PUBKEY DE8B853FC155581D

The firewall is configured according to the manual (https://www.passbolt.com/docs/hosting/configure/firewall-rules/)

Hi roket147

I found a similar post that makes sense. The public key was rotated.

Manually installing the gpg key from the passbolt server should allow you to run the install again and have the repo key.

wget -qO- https://download.passbolt.com/pub.key |\
    gpg --dearmor | sudo tee /usr/share/keyrings/passbolt-repository.gpg > /dev/null
gpg --with-colons --show-keys pub.key | awk -F: '/^fpr:/ {print substr($10, length($10)-15)}'

They you can run the install script again and it should succeed.

Edit: the repository https://download.passbolt.com/ce/ also has instructions

I hope that helps!

cheers
