I have also encountered this problem. In my case I was attempting to install the Flash Player plugin. I used the same sources.list as above (but without intrepid-proposed). The 404 Not Found message was generated by the following packages:
flashplugin-nonfree ia32-libs lib32gcc1 lib32stdc++6 libc6-i386 I looked in the old-releases repository; the files are not there. So I think that this is not a bug in apt but a defect in the intrepid repository. Could the repository be fixed? I think that this is needed in order to follow the upgrade procedure described in https://help.ubuntu.com/community/EOLUpgrades -- old-releases.ubuntu.com missing file for f-spot, mono https://bugs.launchpad.net/bugs/674636 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
