That is what I wondered too.
I always use USB0 on Linux, and only use the other ports in windows.

ttyS0 is usually a physical rs232 port. Are you sure that your laptop has such a port? Or do you use a usb cable and you should use ttyUSB0???

I am running kubuntu 22.04.1 on a Framework laptop.

I have loaded the daily build from flatpak and Chirp
comes up when opened.

My radio is a Baofeng UV-5RV2+

I followed the instructions in:

+
+     Start CHIRP
+     Go to File > New to create an empty CSV file

+     Add a memory to the first row, by entering a frequency

+
+
+     Go to File > Export to save the template file to something
+ ending with a .csv extension
+
+     Open the file in your spreadsheet or external application of
+ choice, make edits and save

+     Re-open the file in CHIRP to validate that the format is
+ still correct, by going to File > Open and choosing your file
+
+     Optionally use File > Import to import the contents of your
+ CSV file into another radio image
+

...

+ If you have a clone-mode radio, upload the changes back to your
+ device using Radio > Upload To Radio. If you are using a
+ live-mode radio, wait until all of the changes finish
+ synchronizing back to the device by watching the status bar in
+ the lower right corner of the main window.

So, when I plug in my radio, I see the following in
/var/logsyslog:

In Chirp I select Radio and slide down to select "Upload
to Radio".

I get a dialogue box saying:Port /dev/ttyS0, Bofeng,
UV5R, I select OK. I get "An error has occurred Could configure
port: (5, 'Input/output error')

So just in case, I fiddles with the /dev/ttyS0
permissions:

crw-rw-rw- 1 root dialout 4, 64 Oct 25 11:15 ttyS0

So what have I not done? What should I do?

Yours
