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 of problem:

If screen server is running, and package is upgraded, updated client can't reattach to running server.

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

4.0.3-18.el6

How reproducible:

I think always

Steps to Reproduce:
1. Install screen-4.0.3-16.el6.x86_64
2. Run screen
3. Detach
4. Update to screen-4.0.3-18.el6.x86_64
5. screen -r -d

Actual results:

Gets stuck

Expected results:

Successfully reconnect, or at least give useful error message

Additional info:

I (naturally) did not know it was related to the upgrade. I searched for "screen reattach stuck" and found [1]. Following that, I downgraded to screen-4.0.3-16.el6.x86_64, and then managed to reattach.
