Ok, in fact I can confirm on cosmic and updating libarchive to the current disco version fixes it, https://launchpad.net/ubuntu/+source/libarchive/3.3.3-4/+build/16358983/+files/libarchive13_3.3.3-4_amd64.deb so it's fixed in the current Ubuntu serie. Could be a bug to SRU fix if someone was wanting to find the corresponding libarchive commit
