I am running Chirp 0.3.0 on Kubuntu 22.04.1 (Jammy Jellyfish)
I have done all below:

A Clean Start
If you want to get an empty CHIRP-compatible CSV file, the easiest way is to let CHIRP create one for you. Here are the approximate steps for creating an empty file, editing it in an external editor and opening it back up in CHIRP:
Start CHIRP
Go to File > New to create an empty CSV file
Add a memory to the first row, by entering a frequency such as 146.52
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
--------
Under File: I do not have an option to Export or Import.
This makes it hard to get my .csv file into Chirp and make it an .img
