Might be related to this, which also has no issue yet.
I am using an MXE-202i mini-PC running Ubuntu Server 20.04 LTS and a nRF52840 dongle to run DFU OTA to program and update nRF52 production devices. I have root access and the port has been added to the dialout group. The command and the error I face is as such:
user@dfuserver:~$ nrfutil -v -v -v -v dfu ble -ic NRF52 -pkg Distribution.zip -p /dev/ttyACM0 -f -cd 30 -n "DfuTarg"

However, it runs successfully on my Windows machine with the same dongle, with the exact same command and without any disconnects. Is this a known issue with nrfutil on Linux?
I am using the latest version(10.9.0) of nRF command line tools and nrfutil as well as Python 3.
