apt-file to find package providing a certain file

Networking on Debian

Debian Network Configuration

Bonding

https

http://www.tuxick.net/docs/apache_ssl.html

https on debian testing is a mess, ignore:

make-ssl-cert
apache2-ssl-certificate in apache2.2-common only?
http://www.debian-administration.org/articles/349

http://www.eclectica.ca/howto/ssl-cert-howto.php looks promising

Handling packages

Compiling Debian Packages

Pinning

HOWTO

Modules

Set module parameters

in /etc/modprobe.d/somename.conf

options somemodule paramname=2

FAQ

Installer

Select a boot disk

Depends a bit, customer installer would insist on that, but expects /boot to be a separate partition?

Check if a reboot is required

Check

/var/run/reboot-required.pkgs

or

needrestart -k -b

change default editor

update-alternatives --config editor

change timezone

dpkg-reconfigure tzdata

Change system language

dpkg-reconfigure locales

and

setlocale

kernel packages

kernel-image
kernel-source

volatile

clean cache

apt-get clean

E: Unable to correct problems, you have held broken packages.

First try

dpkg --get-selections | grep hold

reportbug: The following newer release(s) are available in the Debian archive:

Ignore than and just continue ( see https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=900254 )

apt-get update throwing KEYEXPIRED

Ignore that, it updated just fine. You might run into the usual warnings when installing packaged. To Be Documented. For example:

deb [trusted=yes]

Missing key

Missing key D9A7E9F52B9754A34443ED1DC9A78F8C43D8720A, which is needed to verify signature

Find the key and add it to apt keyring, like

curl -fsSL https://repo.charm.sh/apt/gpg.key | sudo gpg --dearmor -o /etc/apt/keyrings/charm.gpg

Show more package information

apt-cache show packagename*

List installed packages

apt list --installed

W: GPG error:

http://ftp2.de.debian.org etch/volatile Release: The following signatures couldn't be verified because the public key is not available: NO_PUBKEY EC61E0B0BBE55AB3

gpg --keyserver wwwkeys.eu.pgp.net --recv-keys EC61E0B0BBE55AB3
#and that other thing

Or just:

apt-get --allow-unauthenticated install debian-archive-keyring

Or

apt-key adv  --keyserver pgp.mit.edu --recv-keys 8B48AD6246925553

Or

gpg --keyserver keyserver.ubuntu.com --recv-key 03BBF595D4DFD35C
gpg -a --export 03BBF595D4DFD35C | apt-key add -

show dependency tree

apt-cache dotty
apt-rdepends

show dependencies

What depens on package?

apt-cache rdepends <package>

aptitude why

What package does a file belong to?

dpkg -S /path/to/file
