This same error occurs in the Trusty 14.04.2 test of the alternate-i386 ISO.
I get a red failure screen with the error: [!!] Select and install software Installation step failed An installation step failed. You can try to run the failing item again from the menu, or skip it and choose something else. The failing step is: Select and install software Have attached screenshot of failure. Fails on tasksel tasksel: aptitude failed (100) and then WARNING **: Menu item 'pkgsel' failed. Trying to repeat the step fails. If this step is skipped, the system installs without a visible GUI, but there is still a minimal system from the console. ** Attachment added: "Console during failure" https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1417251/+attachment/4312810/+files/Trusty2-Testing.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1417251 Title: in vivid debian installer does not install packages which leads to missing dependencies To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1417251/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
