Not sure, what should be bad with my hardware. The only thing I can imagine is, that my USB-pendrive maybe sometimes has write errors. I attach some screen shots.
In the end, I installed newly Ubuntu on that USB-pendrive. That worked, but I had some other errors that I couldn't log. ** Attachment added: "Screen shot" https://bugs.launchpad.net/ubuntu/+source/perl/+bug/777731/+attachment/2301182/+files/Package%20Operation%20failed.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/777731 Title: package perl 5.10.1-17ubuntu4 failed to install/upgrade: unable to make backup link of `./usr/share/man/man1/shasum.1.gz' before installing new version: Input/output error To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/perl/+bug/777731/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
