@greenjeans
Thanks, but I don't have an hardware switch to shutdown disable the WiFi.
Another way it's to disable it in the BIOS/UEFI (I'll try on my in a couple of hours)

@fanderal
Thanks, I believe you meant: /etc/network/interfaces

in that file I got (I didn't modify it)

auto lo
iface lo inet loopback

indeed I see in /etc/init.d/networking

CONFIGURE_INTERFACES=yes
EXCLUDE_INTERFACES=

If I set CONFIGURE_INTERFACES to no I assum it will affect all the interface
Maybe I can use just EXCLUDE_INTERFACES ? EXCLUDE_INTERFACES=wlan0 ?

Thanks nixer & SSCM

I created a init script /init.d/....

with

inside.

now just remain to test if IPv6 is really disabled ! (any ideas ?)

I also noticed that the third command

gpg -n -q --import --import-options import-show /etc/apt/keyrings/packages.mozilla.org.asc | awk '/pub/{getline; gsub(/^ +| +$/,""); if($0 == "35BAA0B33E9EB396F59CA838C0BA5CE6DC6315A3") print "\nThe key fingerprint matches ("$0").\n"; else print "\nVerification failed: the fingerprint ("$0") does not match the expected one.\n"}'

Is the Public ring is somewhere else on devuan ?

Thanks.

I found !

actually with a fresh install and the etc/apt/sources.list untouched

a "simple"

apt install gcc

works.

if anyone have a good documentation about apt I'm all ears

Thank you all for your reply !

Thank you that have confirmed my thinking. I'm shocked that some people can post "tutorial" without mastering a bit the topic.... Internet peoples..

@boughtonp, oh great indeed I will use also a regex expression in grep to avoid to have the grep itself in the results.

ps aux | grep 'cron$'

BTW I followed those instructions

Installing a Prebuilt Debian Package from the Official NGINX Repository

but when I do an sudo apt update

i get

Thank you @rbit,

btw for future reader, after the upgraded

python -V

was still giving my previous version, but just relaunching the terminal was giving the one just installed.

Cheers.
