One of our webservers which is running Debian
Etch Squeeze (6.0.7) and which we regularly maintain with safe-upgrades (normally it's only a few safe-upgrade packages per week) now shows an abnormally high number of available safe-upgrade packages:
284 packages upgraded, 113 newly installed, 51 to remove and 421 not upgraded.
Is Debian probably forcing Etch users to upgrade to Lenny?
Edit: Server is running Squeeze, not Etch. Looked up the wrong page in our internal wiki.
# lsb_release -a No LSB modules are available. Distributor ID: Debian Description: Debian GNU/Linux 6.0.7 (squeeze) Release: 6.0.7 Codename: squeeze
Therefore, @ptman is right:
/etc/apt/sources.list points to
stable which from now on (May 4th 2013) is Debian Wheezy and no longer Squeeze...
To get safe-upgrades for 6.0.7 squeeze one need to edit
/etc/apt/sources.list and replace
