Public bug reported: I attempted to install Ubuntu 15.10 (64 bit version) from the iso image ubuntu-15.10-desktop-amd64.iso
To do this i created a new 15 G partition on my disk to hold /, and added a menu entry to grub in /etc/grub.d/40_custom in the partition that i'm currently using for 15.04. The entry is menuentry "Ubuntu 15.10 ISO (hd1)" { set isofile="/ubuntu-15.10-desktop-amd64.iso" loopback loop (hd1,34)$isofile linux (loop)/casper/vmlinuz.efi boot=casper iso-scan/filename=$isofile noprompt noeject toram -- initrd (loop)/casper/initrd.lz } and it works, at least in the sense that i could boot into the installation cd iso image. When i booted into the iso image, i clicked on the Install Ubuntu icon, and told it to put the OS on the new partition i had created (/dev/sda35), and it appeared to be doing exactly that. However, after it had been working for a long time (tens of minutes, i believe) a panel popped up that said: "An attempt to configure apt to install additional packages from the CD failed". I clicked OK, and then i got what looked like a normal exit: "Installation finished. You can continue testing Ubuntu now, but until you restart the computer.....". Now, although i can boot into the new partition (i had to force my way in) the installation does not look complete and is certainly not functional. So, e.g., if i log into the guest account, there's no dock or anything else visible, and i have to power-cycle to get out. I've gone through the installation process a few times, and i could run any kind of experiment (i think) while running off the iso experiment, if that would help. ** Affects: ubiquity (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1509603 Title: apt configuration problem in 15.10 installation (failed "to install additional packages") To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/ubiquity/+bug/1509603/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
