This is actually failing before it gets as far as Launchpad. Apache's mod_proxy_http is throwing away the request, something like this (this is from a local development installation, but I verified this against Apache logs from our "dogfood" site):
[Tue Jun 19 20:15:28.820917 2018] [proxy_http:error] [pid 774:tid 3958287168] (70007)The timeout specified has expired: [client 10.36.63.1:56998] AH01095: prefetch request body failed to 127.0.0.1:8086 (localhost) from 10.36.63.1 (), referer: https://bugs.launchpad.dev/redfish/+bug/15/+addcomment It looks like, when AppArmor prevents reading an attachment, Firefox sends request headers with a non-zero Content-Length, but then fails to actually follow up by sending that amount of content. Launchpad can't work around this, because as I mentioned it fails (non-configurably) at the Apache stage before it gets to the webapp. I think the only place this can be fixed is in Firefox. ** Project changed: launchpad => firefox (Ubuntu) ** Tags removed: lp-bugs ui ** Summary changed: - Your browser sent a request that this server could not understand. + sends incomplete request when read access to attachment denied by AppArmor -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1777095 Title: sends incomplete request when read access to attachment denied by AppArmor Status in firefox package in Ubuntu: Triaged Bug description: Hi, I just reported an ubuntu bug #1777094 and wanted to upload the configuration files as attachments (using ubuntu 18.04 and firefox), but I always just get the error message Bad Request Your browser sent a request that this server could not understand. regards Hadmut To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1777095/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
