RHEL Engineering is moving the tracking of its product development work on RHEL 6 through RHEL 9 to Red Hat Jira (issues.redhat.com). If you're a Red Hat customer, please continue to file support cases via the Red Hat customer portal. If you're not, please head to the "RHEL project" in Red Hat Jira and file new tickets here. Individual Bugzilla bugs in the statuses "NEW", "ASSIGNED", and "POST" are being migrated throughout September 2023. Bugs of Red Hat partners with an assigned Engineering Partner Manager (EPM) are migrated in late September as per pre-agreed dates. Bugs against components "kernel", "kernel-rt", and "kpatch" are only migrated if still in "NEW" or "ASSIGNED". If you cannot log in to RH Jira, please consult article #7032570. That failing, please send an e-mail to the RH Jira admins at rh-issues@redhat.com to troubleshoot your issue as a user management inquiry. The email creates a ServiceNow ticket with Red Hat. Individual Bugzilla bugs that are migrated will be moved to status "CLOSED", resolution "MIGRATED", and set with "MigratedToJIRA" in "Keywords". The link to the successor Jira issue will be found under "Links", have a little "two-footprint" icon next to it, and direct you to the "RHEL project" in Red Hat Jira (issue links are of type "https://issues.redhat.com/browse/RHEL-XXXX", where "X" is a digit). This same link will be available in a blue banner at the top of the page informing you that that bug has been migrated.

Comment 2 Gena Makhomed 2021-01-10 23:07:33 UTC
I hit the same bug, but with different error message:

Error unpacking rpm package filesystem-3.8-3.el8.x86_64
  Running scriptlet: systemd-networkd-247.2-1.el8.x86_64
error: unpacking of archive failed on file /proc: cpio: chown

/proc is mounted in rw mode inside systemd-nspawn container:

proc on /proc type proc (rw,nosuid,nodev,noexec,relatime)

# ls -la -d /proc
dr-xr-xr-x 471 nobody nobody 0 Jan  9 09:02 /proc

Hope this help to identify and fix the bug.

Comment 3 Gena Makhomed 2021-02-27 19:40:10 UTC
workaround, run inside systemd-nspawn container:

# echo '%_netsharedpath /sys:/proc' > /etc/rpm/macros.netshared

after this workaround filesystem package will be updated inside systemd-nspawn container without any problems:

# yum update filesystem
