I reproduce this on amd64 with py2.7. It seems a python issue. With py3.6 (at least on amd64) works fine.
I try to upgrade to py3.6 also for ARM arch.

Confirmed with sys-apps/systemd-239-r2.tbz2 built for amd64.

• The package uses the "pax" tar format.
• The problem is with the entries:

filename	item(s)
./var/log/journal	SCHILY.xattr.system.posix_acl_default, SCHILY.xattr.system.posix_acl_access
./var/log/journal/remote	SCHILY.xattr.system.posix_acl_default, SCHILY.xattr.system.posix_acl_access
./var/log/journal/remote/.keep_sys-apps_systemd-0	SCHILY.xattr.system.posix_acl_access

which cannot be decoded as utf8.

• Tarfile from Python 2.7 cannot cope with that.

[Enlik]

It was likely fixed with https://bugs.python.org/issue8633 ("tarfile doesn't support undecodable filename in PAX format"), commit python/cpython@1465cc2, not for Python 2. Issue for Python 2 is https://bugs.python.org/issue26740.

[geaaru]

I confirm that with py3.6 all works fine. I close issue.

[mudler]

Let it open to keep track of it, I still see it in amd64 builds
