Hi All,
I had same problem on Fedora 28, as build machine. After some research i simply decide to use more fresh e2fsprogs where conflict is solved. In same time i use version enough close to default one. I.e. i use 1.43.8 instead of 1.43.3
Take a look at diff files
e2fsprogs-tools.diff
e2fsprogs-utils.diff
