Thank you for taking the time to report this bug and helping to make Ubuntu better. The relevant dpkg terminal log says:
/etc/initramfs/post-update.d//zz-kernelstub: line 7: kernelstub: command not found run-parts: /etc/initramfs/post-update.d//zz-kernelstub exited with return code 127 So /etc/initramfs/post-update.d/zz-kernelstub failed, because the command kernelstub was not found. I found no Ubuntu package that ships the command kernelstub nor I found a package that ships /etc/initramfs/post-update.d/zz-kernelstub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2092577 Title: package initramfs-tools 0.142ubuntu25.4 failed to install/upgrade: installed initramfs-tools package post-installation script subprocess returned error exit status 127 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/initramfs-tools/+bug/2092577/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
