These are not Chirp issues; they are operating system (Linux, Ubuntu) issues. If these notes do not help, get Ubuntu help either through a search or using the Ubuntu support sites.

# Click _Radio_ then _Download from Radio_ at the top menu bar; a window appears with Port, Vendor and Model

# Click Port and from the pull-down list pick the USB option. Usually that is at the bottom of the list with a name like /dev/tty/USB0

# An error window appears with words like *An error has occured*.

# Below the error words is something like *Permission denied*

# Click _Radio_ then _Download from Radio_ at the top menu bar; a window appears with Port, Vendor and Model 
17
# Click Port and from the pull-down list pick the serial port (TTY) with a name like /dev/ttyS0. You may have to experiment to find which port number is active. Another common connection is /dev/ttyS4.

h2. Solution

The most common cause is that the user(s) do not have permission to use the serial-USB connection. Permission must be established for the user. There is much more on this common issue in Linux or Ubuntu wikis and support websites.

# Start a terminal session. 
26
# Enter this this command into the terminal session: @sudo gpasswd --add ${USER} dialout@ 
27
# After executing the command, check that it worked with: @groups ${USER}@ 
28
# The user name will be followed by a list that includes _dialout_. Dialout means permission for the TTY set that includes serial and USB connections.
