Using Debian Long Term Support (LTS)
Important: Wheezy-LTS only supports i386, amd64, armel and armhf. Users of other architectures are encouraged to upgrade to Debian 8 ("Jessie").
The current LTS version is Debian 7 "Wheezy" and will be supported from 2016-04-26 to 2018-05-31. To receive security updates, your /etc/apt/sources.list should look like this one:
deb http://httpredir.debian.org/debian/ wheezy main contrib non-free deb-src http://httpredir.debian.org/debian/ wheezy main contrib non-free deb http://security.debian.org/ wheezy/updates main contrib non-free deb-src http://security.debian.org/ wheezy/updates main contrib non-free deb http://httpredir.debian.org/debian/ wheezy-updates main contrib non-free deb-src http://httpredir.debian.org/debian/ wheezy-updates main contrib non-free
For Debian 7 "Wheezy" LTS there will be no requirement to add a separate wheezy-lts suite to your sources.list any more. In fact you will not notice the switch to LTS because after the official security support by the Debian Security Team ends, security updates will be provided via security.debian.org 's wheezy/updates. See also SourcesList for a general introduction to Debian's sources.list file.
To follow security announcements, you may also want to subscribe to the debian-lts-announce mailing list.
Recommendations for upgrading from Squeeze LTS to Wheezy LTS
Update your /etc/apt/sources.list according to the list above.
Check apt.conf for legacy release pinning. If /etc/apt/apt.conf contains something like this:
APT::Default-Release "squeeze-lts";then you must either comment it out, or replace it with:
Update your system. apt-get update
Install apt from Wheezy before upgrading your system. apt-get install apt -t wheezy
Upgrade your system. apt-get upgrade
Upgrade your system and remove obsolete packages. apt-get dist-upgrade
- Carefully check all debconf prompts and update configuration files as needed.
If you want more info on which mirrors to use, read debian mirrors.
Check for unsupported packages
Not all packages of the Debian archive are supported by Wheezy LTS. To check whether you have unsupported packages installed on your machine, please install the debian-security-support package (use the version in wheezy, unstable will not work as expected). A check for new unsupported packages is run every time packages are installed. You can also run the 'check-support-status' utility manually to get a list of all unsupported packages installed on your system.
What can I do if security support for a package has ended?
You can choose between different options:
- Remove the unmaintained package.
- Keep the software and make sure, that neither already known nor new security issues affect your system.
