Resolved Update: apparently cat cannot write to /etc. Resolved by using:

sudo tee /etc/apt/sources.list.d/mozilla.sources <<eof types: deb uris: https: packages.mozilla.org apt suites: mozilla components: main signed-by: etc keyrings packages.mozilla.org.asc eof p></eof>

The instructions need updating!

_________________original problem (in case some one else needs the information)

I am following the instructions in section "Install Firefox from Mozilla Repository (Recommended)" at https://support.mozilla.org/en-US/kb/run-firefox-chromeos At step 4 I am receiving a permission denied error: "-bash: /etc/apt/sources.list.d/mozilla.sources: Permission denied" I am not sure how to resolve or continue.

Last command and output:

username@penguin:~ cat <<EOF > /etc/apt/sources.list.d/mozilla.sources Types: deb URIs: https://packages.mozilla.org/apt Suites: mozilla Components: main Signed-By: /etc/apt/keyrings/packages.mozilla.org.asc EOF -bash: /etc/apt/sources.list.d/mozilla.sources: Permission denied

Hello, the official mozilla page instructions for how to download Firefox for Linux (Debian 13) is wrong, it fails on Step 3 saying that the key verification is incorrect thus I have not tried the steps after 3.

I know Debian 13 comes with Firefox ESR but from my research this is packaged and maintained by Debian, I would prefer it if all my eggs were not in one basket and I actually had the real source maintainer updating my browser aka Mozilla.

I don't know what else to say, it is just incorrectly written or something, because Brave Browsers installation instructions are SOO much better and simpler, super easy works 10/10 times, and it's way fewer commands.

Please help, thanks!
