ckermit-raymii banner


This is the Ubuntu 18.04 .deb package converted to snap, because in Ubuntu 20.04, there is no ckermit package. Just as I did with Gnash. See for more info on the snap, and for more info on kermit. The snap source code is here:

This is not an official kermit-project package.

C-Kermit is a combined network and serial communication software package offering a consistent, transport-independent, cross-platform approach to connection establishment, terminal sessions, file transfer, file management, character-set translation, numeric and alphanumeric paging, and automation of file transfer and management, dialogs, and communication tasks through its built-in scripting language.

The Kermit Project originated at Columbia University in New York City in 1981 and remained there for 30 years. Since 2011 it is independent.


In order to access a serial port over USB (ttyUSB0 for example, you need to add your user to the dailout group and connect the snap to the raw-usb socket.

Open a terminal window, run the following commands an reboot your computer.

sudo usermod -a -G dialout $USER

sudo snap connect ckermit-raymii:raw-usb

Now restart your computer and you're good to go!
