Debian 7 (Wheezy) is the most recent stable version of Debian Linux, released in May 2013. This guide explains how to upgrade your system from Debian 6 (Squeeze) to Debian 7. These steps can be preformed as an in place upgrade on a live system from either a local terminal or SSH session to a remote system. Comment out everything else in /etc/apt/sources.list by adding a # at the start of every entry. only the above line should be uncommented. Run the following command as root apt-get update Repeating apt-get update does not resolve the problem. My experience and other threads in this forum suggest that the problem is a messy sources.list with duplicate entries. This works for the domain name deb.debian.org but not for security.debian.org. Any idea if we can use HTTPS for both domains? It looks like the certificate of security.debian.org is not valid. By the way, HTTPS should be the default, I don't understand why they provide it as an option to enable manually – baptx May 25 '19 at 9:16 Check the apt sources.list file We will install all available Jessie updates first before we upgrade to Jessie. On some systems, the package source is defined as "stable" in the sources.list file instead of "jessie" or "stretch". I want to use testing-distribution (currently thats "wheezy" instead of the stable "squeeze") of Debian, and am about to adjust my /etc/apt/sources.list file. I know that I have to replace squeeze by wheezy for the main entry. But do I have to do this for security (squeeze/updates) and updates (squeeze-updates) too? Apr 26, 2015 · The process involves fully updating your Debian 7 installation, modifying the /etc/apt/sources.list file by changing instances of “wheezy” to “jessie”, running an ‘apt-get update’, ‘apt-get upgrade’, followed by a ‘apt-get dist-upgrade’ and then finally a reboot so that the newer kernel version will be used.
To change the content of my sources.list i use 'gksu gedit etc/apt/sources.list'. If UP3 will be available i'll show up the new list in point 1.1 above and you then can copy and paste it to your list. The old lines can be deleted then.
You must edit your /etc/apt/sources.list to replaces the old repository name by the new one. Little explanation about the domain name change, Debian asked me to stop using the word debian. You can read the DPL message here. 06/07/2019 : Repository updated for buster. Enjoy. 22/03/2019 : Wheezy has been moved to https://archive.deb-mulimedia.org Add A Debian Repository – Linux Hint
Just a caveat here. If you're dealing with some problem where you've got incorrect settings in /etc/apt/sources.list, e.g. a disk is expected, it's probably a good idea to to rewrite the file from scratch.. To do this for Debian I just used https://debgen.simplylinux.ch/ to generate the file.. Initially I just tried just removing the reference from sources.list as recommended, but then I
