Public bug reported: Bionic beaver 18.04 libguetfs-tools 1:1.36.13-1ubuntu3:
sudo apt-get install libguestfs-tools mkdir sysroot # Just a test file. dd if=/dev/urandom of=sysroot/myfile bs=1024 count=1024 sudo virt-make-fs --format=qcow2 --type=ext2 sysroot sysroot.ext2.qcow2 fails with: libguestfs: error: tar_in: write error on directory: /: Without sudo: virt-make-fs --format=qcow2 --type=ext2 sysroot sysroot.ext2.qcow2 fails with: libguestfs: error: /usr/bin/supermin exited with error status 1. To see full error messages you may need to enable debugging. Do: export LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 and run the command again. For further information, read: http://libguestfs.org/guestfs-faq.1.html#debugging-libguestfs You can also run 'libguestfs-test-tool' and post the *complete* output into a bug report or message to the libguestfs mailing list. but I think it is an unrelated problem. Original command with debug vars: sudo LIBGUESTFS_DEBUG=1 LIBGUESTFS_TRACE=1 virt-make-fs --format=qcow2 --size=+200M sysroot/ output.img attached as a file. ** Affects: libguestfs (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1777058 Title: virt-make-fs fails with: "libguestfs: error: tar_in: write error on directory: /:" To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libguestfs/+bug/1777058/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
