* 2020-01-13: initramfs problem fix: https://ubuntuforums.org/showthread.php?t=1990236
* 2019-07-08: Thunderbird stopped syncing mail; IMAP server not supporting the authentication method; had to fix dovecot; used this bug report https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=924580 and https://b4d.sablun.org/blog/2019-02-25-dovecot_2.3_upgrade_on_debian/ as main guidance.
* bluetooth not connecting; installed blueman, pulseaudio-module-bluetooth, rfkill unblock bluetooth, killall pulseaudio (one or more of those) fixed it; https://wiki.debian.org/BluetoothUser/a2dp
* sid = unstable but pretty stable. 
* Look at packages.qa.debian for todo's and qa.debian under my name for all the bugs and other information.
* Popcon means popularity contest but there are people who install a package but don't use popcon.
* dpkg -l (package name): gives the version of the package.
* dpkg --audit: get a list of broken packages.
* dpkg --configure (package name):amd64 if I get apt-get install errors saying ambiguous packages and if audit is showing multiple architectures and if I don't have muliarch-support for some reason. Make sure to not put space after : before amd64.
* To get the system up to date:
** apt-get update (Used to re-synchronize the package index files from their sources. And then;)
** apt-get upgrade
* To upgrade to Squeeze (except I wanted testing = Wheezy):
** change previous (lenny) to (latest) squeeze in /etc/apt/source.list 
** apt-get update
** apt-get install apt dpkg apt
** apt-get dist-upgrade: error message telling me /var/cache/apt/archives doesn't have enough space. Ran aptitude clean and it was cleaned up.
** I changed to Wheezy because I wanted Gnome3.2. I changed on the /etc/apt/source.list.
** I changed to jessie in /etc/apt/apt.conf
* pitivi wasn't as good as dpic's. He said to do:
** apt-get build-dep pitivi: Normally, specific headers and shared libraries need to be present in order for a source package to be compiled. All source packages have a field in their control files called 'Build-Depends:' that indicates which additional packages are needed for the package to be built from source. APT has a simple way of downloading these packages. Just run apt-get build-dep package, where `package' is the name of the package you're going to build. 
** git clone git://git.gnome.org/pitivi
** cd pitivi
** ./autogen.sh && ./configure && make (make is an essential program for installing much unpackaged source code software. The developers can write down all of the complex information about how to configure, compile, and install their work in make files that you usually won't have to read. Just check README or INSTALL files that come with the source code to see whether it uses this system, or has different instructions. Another program with similar functions is jhbuild.
** bin/pitivi
** after upgrading, the sound stopped working. No volume button on Gnome toolbar and no output/input devices in the settings. I did the following and rebooted, which restored the sound:
:: sudo apt-get remove --purge alsa-base
:: sudo apt-get remove --purge pulseaudio
:: sudo apt-get install alsa-base
:: sudo apt-get install pulseaudio
:: sudo alsa force-reload
** after upgrading, calendar/iceowl in icedove didn't work. I had to reinstall iceowl-extension, which removed enigmail. I reinstalled enigmail after installing iceowl.
** when a computer shuts down unexpectedly, check /var/log/kern.log and see what happened right before the reboot.
** apt-get install -f <package name>:unstable to install unstable. <package name>=<version number> to install specific version number.
** the time was a few minutes earlier. Fix: /etc/init.d/ntp restart.
