Forgot to mention that the proxy was preseeded: ubiquity mirror/http/proxy string http://10.0.2.9:3142/
In IRC, xnox suggested configuring a global proxy in network-manager, and that does work for the language packs: Active Internet connections (servers and established) Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name tcp 0 0 10.0.254.133:58356 10.0.2.9:3142 TIME_WAIT - tcp 0 0 10.0.254.133:893 10.0.2.1:2049 ESTABLISHED - tcp 0 0 10.0.254.133:58357 10.0.2.9:3142 ESTABLISHED 10345/http tcp 0 0 10.0.254.133:57483 91.189.92.60:80 ESTABLISHED 3667/python3 (In my case 10.0.2.9:3142 is not a general http proxy but only an apt- cacher-ng, so that does break e.g. Firefox in the live session, but it does work for installing.) The http process is a child of plugininstall.py and runs in the host, not the target: init───lightdm───lightdm───init───sh───udisks2-inhibit───ubiquity───log- output───plugininstall.p───http His other suggestion was to disable downloading the language packs at install time. Preseeding "ubiquity pkgsel/install-language-support boolean false" does that, so that's a good workaround. (Not quite ideal, though, because /var/lib/update-notifier/user.d/incomplete-language- support-*.note aren't created; is that a bug?) plugininstall.py already seems to respect some other apt settings, maybe it wouldn't be hard to teach it about mirror/http/proxy as well? If I find time I'll see about a patch.
