Thanks for the Answer.
I already have the basics of UbuntuTouch on my phone. The installation always stops at the last point "Flash"... could this be related to a correct USB connection? Since the mobile phone's controls work from the Linux PC via Terminal and ADB, the question is whether the USB connection is lost? Fastboot Mode PROD_NAME = lito, VARIANT = SM_ UFS, SERIALK NR = BA596ED6, SECURE BOOT = YES, DEVICE STATE = UNLOCK Attached are the steps one after the other that I do with the software on the PC (UBports Installer) From picture 2 the USB connection is gone ? and in picture 3 "Fastboot" I select the item "Reboot to Bootloader" and am in FASTBOOT MODE! But without USB connection. Even if I unplug and replug the cable, USB won't connect!

Here is the entire error_line:
Error: fastboot: flash :error Error: Flashing failed : {"error":{"code":1}, "stderr":"FAILED (remote: 'Flashing is not allowed for Critical Partitions')fastboot: error: Command failed"}
