Still no solution for unprivileged containers? I have kernel 4.15.18-16-pve #1 SMP PVE 4.15.18-41 (Tue, 18 Jun 2019 07:36:54 +0200) x86_64 GNU/Linux but I still cannot update package filesystem.x86_64 0:3.2-21.el7
But i'm still stuck with iputils.
Error unpacking rpm package iputils-20160308-8.el7.x86_64
error: unpacking of archive failed on file /usr/bin/ping;585aafa1: cpio: cap_set_file
iputils-20121221-7.el7.x86_64 was supposed to be removed but is not!
