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 Takahiro HASHIMOTO 2021-01-19 11:57:39 UTC
Description of problem:

Anaconda GUI installation crashes when ntp setting dialog is opened with incorrect IP and DNS server settings.

Version-Release number of selected component (if applicable):

CentOS Stream 8 

How reproducible:

Almost always (occurred 3 times in 4 attempts in my environment)

Steps to Reproduce:
1.  Boot with CentOS Stream 8 install ISO and launch anaconda GUI installer
2.  Click "System->Network & Host Name" button to open network settings pane
3.  Enable and set options of  the Ethernet  adapter which is used to communicate with ntp server as following
  a. IPv4 settings :  set to manual, configure a IP address and incorrect gateway address(not gateway)
  b. Additional DNS servers:  set DNS server address which cannot be reachable or incorrect(not DNS server) 
  c. (optional) disable IPv6 
4. Push "Done" button to exit Network settings
5.  Push "Localization-> Time & Date" button to open time and date settings pane
6.  Confirm the caution in the bottom of screen with the message "You have no working NTP server configured"
7.  Click  the "gear" icon button on the upper-right of screen to open NTP server configuration and wait for some seconds(about 10-20)
8. Confirm anaconda is crashed with the dialog "An unknown error has occurred

Actual results:

Anaconda installer is crashed.

Expected results:

Anaconda installer worked fine, ntp dialog can be modified.

Additional info:

I've attached two screenshots.

1. anaconda GUI screenshot with error
2. python stacktrace in /tmp/anaconda.log screenshot

When the dialog is opened, some multiple threads seems to be invoked which check if the ntp servers in the model(list) is working or not. The error seems to be occurred in handling the threads.

I've confirmed that this issue is also occurred on the RHEL 8.3 installer.

Comment 4 Jan Stodola 2021-03-17 15:49:38 UTC
See also bug 1938168 - most probably the same problem.

Comment 5 Jan Stodola 2021-03-23 10:17:36 UTC
This problem will be fixed in bug 1938168, so I'm closing this one as a duplicate.
