@Michael: Well, it is just simple authentication. Here's what i did: $ sudo env | grep http_proxy; sudo /usr/bin/do-release-upgrade [sudo] password for user: http_proxy=http://user:passw...@proxy.abc.de:3128/ Checking for a new ubuntu release No new release found
If i modifiy the mentioned python script to print out the error code it says 407. A "wget http://changelogs.ubuntu.com/meta-release" works without problems. -- url_downloadable ignores proxy settings https://bugs.launchpad.net/bugs/446552 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
