Hi Phillip,
first please note that Secure Provisioning v6 is tested on Ubuntu 22.04, as stated in the ReleaseNotes.txt, section System requirements:
- One of the following Host Operating systems:
- Microsoft(R) Windows(R) 10 (64-bit)
- Mac OS 12.4 Monterey
- Ubuntu 22.04 LTS 64 bit, with "OpenSSL 1.1.1f 31 Mar 2020"; GNOME recommended
Second, it works for me even on Ubuntu 20.04 LTS as you require. It might be some issue in your workspace, if you already have Secure Provisioning installed. Anyway, troubleshooting can be done if you execute the tool in the Terminal, so we can see some error messages that might lead to the root cause:
/opt/nxp/MCUX_Provi_v6/bin/securep
There might be some missing package in the Linux box.
Regards,
Libor
