Description

As soon as named channels have been created, you can no longer add context to all channels:

$ lttng add-context --help
usage: lttng add-context -t TYPE [-k|-u] [OPTIONS]

If no channel is given (-c), the context is added to
all channels.

Otherwise the context is added only to the channel (-c).
