Some time ago the lxc configuration did some renaming of options, notably lxc.network to lxc.net. In commit 413f15d we adapted partially for that, but the conversion of the local proxy to the testbed proxy fails because it only tests for lxc.network.link in the following block (in autopkgtest-build-lxc and autopkgtest-build-lxd): local bridge_interface=$(awk '{ if ($1 == "lxc.network.link") print($3)}' /etc/lxc/default.conf) Mind that fixing this bug might mean that people relying on the proxy not set might want to see bug 933064 fixed or otherwise we break work flows. (Hence the block by). Note also that lxc.network is not backwards supported on trixie, so backwards compatibility support has already been removed for some time: lxc-create: autopkgtest-testing-amd64.new: ../src/lxc/confile.c: set_config_unsupported_key: 164 Invalid argument - Unsupported config key "lxc.network.type" Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8), LANGUAGE=en_US:en
