Try with --no-cleanup`. This will give you a temporary folder with a
`flash_devkit.lst` (or similar) file. Then do `uuu flash_devkit.lst`
which should give you a better error message. It's usually either
permissions  (see the librem5-devkit-host package with udev rules
to fix that up if you want to run as regular user) or too old uuu
versions (the ones in Debian bullseye and PureOS Byzantium are known
to be recent enough).
