Dear Purism Community,
Here is an alternative method to create an SD Card that will automatically decrypt on the Librem 5 utilizing GNOME Disks. The application should be preinstalled on the device
Before doing these steps check out this thread. It appears that GNOME may have some issues but let me know if I am wrong:
- Shutdown and Insert your SD card into the Librem 5.
It fits alongside your SIM Card in your SIM card tray.
-
Open GNOME Disks from the application menu.
-
Select the SD card from the list of storage devices on the left.
-
Format the SD card by clicking the gear icon and selecting “Format Partition…”
-
Click the + sign
You will then wanna select “Internal disk for use with Linux systems only” as well as "Password protect volume (LUKS)
It should prompt you for the encryption password.
- Set up automatic decryption:
- Open the “Disks” menu at the top-right of the GNOME Disks application.
- Go to “Edit Encryption Options.”
- Swipe to the left “Session Defaults”
- Check the option “Unlock at system startup”
- Make sure to fill in the section titled “passphrase” with the associated encryption password
Formatting will erase all existing data.
