I'm also seeing issues with the GPG-keys in 2.9.3. I just did a fresh install from the iso found on
linuxcnc.org/downloads/
and the first command i ran was:
Code:
thomas@LinuxCNC-dev:~$ sudo apt update

...not sure why it isn't working...
I'm but no means a Linux guru, so my attempt to fix this was to try to jumble together a solution from this thread. I ended up fetching a new key:
Code:
KEYRING=/usr/share/keyrings/ethercat.gpg && curl -fsSL https://download.opensuse.org/repositories/science:/EtherLab/Debian_12/Release.key | gpg --dearmor | sudo tee "$KEYRING" >/dev/null
...but that didn't work, so i ended up deleting the old keys and copying the new one into their place:
Code:
sudo rm /etc/apt/trusted.gpg.d/science_EtherLab.gpg.key.*
sudo cp /usr/share/keyrings/ethercat.gpg /etc/apt/trusted.gpg.d/science_EtherLab.gpg.key.binary.gpg
sudo cp /usr/share/keyrings/ethercat.gpg /etc/apt/trusted.gpg.d/science_EtherLab.gpg.key.chroot.gpg
...i'm pretty sure this isn't the correct way to fix it, but now i can run apt update without errors. Maybe it can help someone else. I believe this is a bug in 2.9.3, since it was a completely fresh install(with available internet connection) and it was literaly the first command i ran and it failed...
Thanks!
