Disables APT pipelining on first boot for new Cloud Images instances - 2.) Disables APT pipelining on installation for existing cloud-images. + 1.) Disables APT pipelining on first boot for new Cloud Images instances + 2.) Disables APT pipelining on installation for existing cloud-images. The rational for this SRU is due to the Mirror situation for EC2 Cloud images. Currently, the mirrors are proving to have moments of instability that is causing both end-user and development pain. In order to address this, we built out Amazon AWS S3 mirrors. Unfortantly, due to a bug in S3, apt http pipeling does not work with S3. As a result, in order to provide enhanced availability for the Cloud Image repositories in EC2, apt http pipelining needs to be disabled ahead of flipping the new S3 mirrors as the active mirrors. The performance impact of this change is unnoticable and in testing, has proven to provide no ill effect. http pipeplining allows for multiple requests to be made at the same time. The apt change log states that http pipelining is a "micro-enhancement" and within the EC2 environment shaves a few seconds of many requests. When apt http pipeling works, at best, it saves a few seconds, when it fails against a buggy HTTP1.1 server or behind a proxy that does not support it, the failures are arbitrary and not adiquetly explained. This change will enhance the Cloud Images by making apt request packages sequentially instead of in batches and prevent arbitrary failures caused by non-compliant web servers. Cloud image users, both on EC2 and outside, will benefit from this fix. http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/revision/536 http://bazaar.launchpad.net/~cloud-init-dev/cloud-init/trunk/revision/537 - _______________________________________________________________________________________ apt-get is appears to be mangling the local caching file names, which is appearing as a hashsum or size mismatch.

Currently it comes with the following main features: . - Programming language independent D-Bus interface, which allows one to write clients in several languages - Runs only if required (D-Bus activation) - Fine grained privilege management using PolicyKit, e.g. allowing all desktop user to query for updates without entering a password - Support for media changes during installation from DVD/CDROM - Support for debconf (Debian's package configuration system) - Support for attaching a terminal to the underlying dpkg call . This package contains the aptd script and all the data files required to run the daemon. Moreover it contains the aptdcon script, which is a command line client for aptdaemon.
