I have the same problem... I have changed repository but nothing happened...
I tried to change the file: /etc/apt/sources.list.d/prerequists- sources.list # sources.list fragment for pre-requists (one with countrymirror, one fallback) deb http://fr.archive.ubuntu.com/ubuntu feisty-backports main/debian-installer #deb http://archive.ubuntu.com/ubuntu feisty-backports main/debian-installer # below is just for testing #deb http://archive.dogfood.launchpad.net/ubuntu feisty-backports main/debian-installer in # sources.list fragment for pre-requists (one with countrymirror, one fallback) deb http://be.archive.ubuntu.com/ubuntu feisty-backports main/debian-installer #deb http://archive.ubuntu.com/ubuntu feisty-backports main/debian-installer # below is just for testing #deb http://archive.dogfood.launchpad.net/ubuntu feisty-backports main/debian-installer but when you launch the "update-manager -c" command, there is a reinitialization of the file. How can I block edition of this file to update-manager? -- Kubuntu 7.10 distribution update applet crashes owhen updating https://bugs.launchpad.net/bugs/154803 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
