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.

Description Brian Lane 2020-08-26 21:02:27 UTC 
Description of problem:
Some people expect to be able to use mock from EPEL 8 with livemedia-creator. The new RHSM feature prevents this from working because it always tries to start the rhsm.service (you can't run a systemd service inside mock) so the livemedia-creator run fails.


Version-Release number of selected component (if applicable):
anaconda-tui-33.16.3.21-1.el8
lorax-28.14.54-2.el8
lorax-lmc-novirt-28.14.54-2.el8

How reproducible:
always

Steps to Reproduce:
1. Install EPEL8 repository
2. Install mock from EPEL8
3. Create a new mock config pointing to a local RHEL 8 repo
4. mock -r rhel-8-x86_64 --init
5. mock -r rhel-8-x86_64 --install lorax-lmc-novirt
6. mock -r rhel-8-x86_64 --copyin ./test.ks /root/
7. mock -r rhel-8-x86_64 --enable-network --chroot -- livemedia-creator --no-virt --make-fsimage --ks /root/test.ks


Actual results:
Anaconda fails with an error - "dasbus.error.DBusError: The RHSM DBus API is not available."


Expected results:
anaconda runs and doesn't try to start the rhsm service unless the rhsm command is included in the kickstart (or it is running without kickstart).

This is a valid issue - I guess we should add code that detects Anaconda is running in mock and does not attempt to communicate with the RHSM service. Due to this Anaconda will not be able to resgsiter & use the CDN, as the only usable RHSM API is provided via DBUS, but that might not be an issue for LMC.

You can use the certs with the url and repo --ssl* arguments, but that has to be setup manually and in general I wouldn't expect someone running inside mock to be doing that.
It might work to make the rhsm startup a soft failure, and then exit if fetching packages doesn't work. Or detect the error from systemctl start rhsm, but that may not be very reliable. I get this output/rc:


<mock-chroot> sh-4.4# systemctl start rhsm
System has not been booted with systemd as init system (PID 1). Can't operate.
Failed to connect to bus: Host is down
<mock-chroot> sh-4.4# echo $?

Comment 7 Massimiliano 2020-12-18 16:04:55 UTC 
I'm trying to build a live image with CentOS Stream:
$ cat /etc/redhat-release 
CentOS Stream release 8

$ rpm -q anaconda-tui lorax-\*
anaconda-tui-33.16.3.26-1.el8.x86_64
lorax-28.14.55-2.el8.x86_64

I'm facing this issue if I run the command:
$ mock --root=centos-8-remix-x86_64 --isolation=simple --chroot -- livemedia-creator --no-virt --nomacboot --tmp=/results --logfile=/results/logs/livemedia.log --make-iso --project=CentOS --releasever=8 --ks=/results/gnome-box.ks

But if run the following, then the process goes on:
$ mock --root=centos-8-remix-x86_64 --isolation=simple --chroot -- livemedia-creator --no-virt --nomacboot --tmp=/results --logfile=/results/logs/livemedia.log --make-iso --project=Fedora --releasever=8 --ks=/results/gnome-box.ks

Note the option "--project=Fedora" instead of "--project=CentOS".

I realized that I need to set "--project='CentOS Stream'", I suppose in order to match the configuration file /etc/anaconda/product.d/centos-stream.conf

The anaconda log chunk:
