I've just noticed in your screenshot rpi-imager is not displaying the name of your custom manifest file in the window title, so I suspect it's not loading it.Repeated the test with a fresh install of Trixie 64-bit Desktop (and ~123 updates) on a Pi4
Same result "Interfaces and Features" is not shown.
The process is running with the local json from ps:Code:
/tmp/.mount_rpi-immCmPdC/usr/bin/rpi-imager file:///home/pi/local/os_list_local.rpi-imager-manifest/usr/bin/rpi-imager file:///home/pi/local/os_list_local.rpi-imager-manifest
Try added the '--repo' parameter, or use the 'App Options -> Content Repository -> EDIT' option in the GUI.
Also, I'm not sure you need the 'file:' prefix...
Example:
Code:
rpi-imager --repo /home/pi/os_list_local.rpi-imager-manifestThis command results in rpi-imager failing to load the custom manifest file and quietly loading the online one instead, so you probably wouldn't notice:
Code:
pi@rpi5nvme:~ $ rpi-imager file:///home/pi/os_list_local.rpi-imager-manifest [snip]Manifest file not found: file:///home/pi/os_list_local.rpi-imager-manifest[snip]Code:
