Which archs are supported?

The archs i386 and amd64 only are supported.

Additionally, a few packages will not be supported in the LTS version of the release, primarily some web-based applications which cannot be supported for the additional timeframe. The tool check-support-status from the package debian-security-support helps to detect such unsupported packages. (As of June 2014 the package is in squeeze-lts and in sid, but https://packages.debian.org doesn't list squeeze-lts. The bug is already reported)

What about non-i386 and non-amd64 archs?

Please update to DebianWheezy. See section 4 of the ReleaseNotes

What is the time frame for Squeeze LTS?

LTS starts at the end of may 2014, after the End of Life of squeeze (end of being oldstable). LTS support ends on 6th of february 2016. See DebianSqueeze#Debian/Squeeze_Life_cycle for more details.

Who will provide updates for LTS?

The release will not be handled by the Debian security team, but by a separate group of volunteers and companies interested in making it a success (with some overlap in people involved). Companies using Debian who are interested in aiding this effort should contact the mailing list debian-lts.

Where can bugs be reported?

Please report bugs that you found in the packages to the debian-lts mailing list. The bar for severity will be raised (minor issues will no longer be fixed).

Will there be wheezy-lts?

Squeeze LTS is a first time experiment. It will be considered later whether there's LTS for wheezy as well or again for jessie.

What are the reasons for not using security.debian.org for the LTS security updates?

security.debian.org is (reasonably enough) quite locked down, and wasn't built for adding new suites as easily as the main archive. (from https://lists.debian.org/debian-lts/2014/06/msg00065.html)

Who fixes security issues with packages in squeeze-backports?

Backports isn't LTS-land. The backporter is responsible in updating his backport if needed [1]. Security issues in squeeze-backports are handled the very same way they were handled when squeeze was stable and supported directly. (Source)

I am getting "Install these packages without verification [y/N]" although worked before etc.

Try disabling in apt/apt-get update/re-enabling in apt/apt-get update in your APT configuration (Source)
