For the oldstable distribution (squeeze), these problems will be fixed soon in 1.24-3+squeeze1 (due to a technical restriction in the archive processing scripts the two updates cannot be released together).

For the stable distribution (wheezy), these problems have been fixed in version 1.24-3.1+deb7u2.

For the unstable distribution (sid), these problems will be fixed soon.

We recommend that you upgrade your chrony packages.");
