Hellow~ Actually i am new to Debian. Especially i did install Debian 11 Bullseye udner Chrome OS (ARM64 MT8173 Chromebook). Before i used Ubuntu 18.04 LTS. My question is: Is this canonical way? #+BEGIN_SRC: sh soyeomul@penguin:/etc/apt$ cat sources.list deb https://deb.debian.org/debian bullseye main soyeomul@penguin:/etc/apt$ #+END_SRC That is only one line. Thanks for any comments! Sincerely, Byung-Hee
