I have a similar problem. For me the Ubuntu 20.04 installer would consistently crash at 90% (regardless of which hard drive I installed it to). When I followed the instructions to report the bug, it led me here.
I was able to circumvent the problem by choosing "minimal installation" and NOT "download updates while installing". That made the installation succeed. It might be caused by bad hardware on my system. I don't know. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1871268 Title: Installation fails with Could not configure 'libc6:i386'. , E:Could not perform immediate configuration on 'libgcc-s1:i386' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-cdimage/+bug/1871268/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
