Unfortunately there doesn't appear to be anyway to use this work around with update-manager, causing feisty -> grumpy upgrades to fail.
If this failure was indeed caused by this bug, if there is some way of causing update-manager to use those apt flags it would provide a workaround. ** Attachment added: "Update manager logs from attempted feisty->gutsy upgrade" http://launchpadlibrarian.net/9670024/dist-upgrade.tar ** Also affects: update-manager (Ubuntu) Importance: Undecided Status: New ** Summary changed: - BADSIG errors on http proxies (transparent?) + BADSIG errors using transparent http proxies ** Description changed: - I am still regularly getting signature validation errors with apt-get - update, even when running with -o Acquire::BrokenProxy=true. + Users forced to use substandard proxies, such as many users in Thailand, + regularly get signature validation errors with apt-get update and all + the tools that rely on apt such as update-manager and synaptic.
