PR submitted by author to fix the issue - thank you! https://github.com/rhinstaller/anaconda/pull/3107 See https://github.com/rhinstaller/anaconda/pull/3295 which links most of the related developments since last time posted here. Last developments in https://github.com/rhinstaller/anaconda/pull/3304 PR merged. Looks like this bug was from the beginning for RHEL 8, although I treated it as for Rawhide. Sorry. That means all links above are upstream only. But from now on, let's keep it for RHEL 8. PR merged. Tested with anaconda 33.16.5.2-1.el8 If network is enabled, ip=dhcp on kernel cmdline, it works as expected. Anaconda informs that X did not start and offers to continue installation via VNC or text mode. If network is not enabled, anaconda throws exception and user cannot continue with the installation. See attached logs. Created attachment 1788865 [details]
Logs from 33.16.5.2-1.el8
After discussion and more testing we found that the reproduction steps were causing unrelated issue. Pre-verified - anaconda 33.16.5.2-1.el8 in RHEL-8.5.0-20210524.t.19 anaconda-33.16.5.1-1.el8 is present in compose RHEL-8.5.0-20210622.n.0, moving to VERIFIED. Since the problem described in this bug report should be resolved in a recent advisory, it has been closed with a resolution of ERRATA.

Description of problem: There's a logic bug here In function startX at pyanaconda/core/util.py the program triggers a timeout and executes sigalrm_handler When the Xorg service starts too slowly and exceeds the timeout time, which executes the raise exiterror causing the finally block to be executed. The finally block will cancel processing of the SIGUSER1 signal, which will cause the signuser1 sent to Anaconda after the Xorg service is started to fail to process and the program will die Version-Release number of selected component (if applicable): anaconda 33.17 How reproducible: In the function startX add code `time.sleep(0.5)` after the code `signal.alarm(timeout)` and add boot options: inst.xtimeout=1 Steps to Reproduce: 1. add code `time.sleep(0.5)` after the code `signal.alarm(timeout)` in function startX 2.make a new setup iso 3.add boot options: inst.xtimeout=1 Actual results: X startup failed, falling back to text mode Pane is dead(signal 10, date) Expected results: X startup failed, falling back to text mode no other failed and i can setup os through text mode Additional info: NA
