I had a similar issue yesterday - not during release upgrade but when installing package updates (Ubuntu 21.10):
package libc6 2.34-0ubuntu3.2 failed to install/upgrade: unable to open '/lib/x86_64-linux-gnu/ld-linux-x86-64.so.2.dpkg-new': Text file busy The way I resolve it is via dual-boot, I boot to alternative installation, I mount the one which I want to update to let's say /mnt and I do: dpkg -i --root=/mnt libc6.....deb This leads to an error "too many levels of symbolic links" but after that I can login to my main installation and finish the package updates. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1943124 Title: Upgrade fails due to "text file busy" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/glibc/+bug/1943124/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
