Hi Micah- thanks for getting back to me. I uninstalled the 3.8.0-1.1 version and ran the commands below.
Successfully installed darktable 3.8.1
Still not recognizing camera in old or recently imported files.
Anything more I can provide for trouble shooting?
echo 'deb http://download.opensuse.org/repositories/graphics:/darktable/xUbuntu_20.04/ /' | sudo tee /etc/apt/sources.list.d/graphics:darktable.list
curl -fsSL https://download.opensuse.org/repositories/graphics:darktable/xUbuntu_20.04/Release.key | gpg --dearmor | sudo tee /etc/apt/trusted.gpg.d/graphics_darktable.gpg > /dev/null
sudo apt update
sudo apt install darktable
No such problem with the flatpak.
