Description Bruno Goncalves 2019-11-19 10:22:09 UTC

Description of problem:
After upgrading glibc to glibc-2.30.9000-18.fc32 it was not possible to login to VM.

We boto a VM using Fedora Rawhide qcow2, after we upgrade to glibc-2.30.9000-18.fc32 we can't ssh to it. With glibc-2.30.9000-17.fc32 it works well.

Version-Release number of selected component (if applicable):
glibc-2.30.9000-18.fc32

How reproducible:
100%

Steps to Reproduce:
1.Get qcow2 from https://jenkins-continuous-infra.apps.ci.centos.org/view/all/job/fedora-rawhide-image-test/lastSuccessfulBuild/artifact/Fedora-Rawhide.qcow2

Currently is Fedora-Rawhide-20190920.n.1

2.ssh to the VM
in this case:

ssh -p 2619 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i /tmp/inventory-cloudjqqtug44/identity root.0.3

3.update glibc
dnf update https://kojipkgs.fedoraproject.org//packages/glibc/2.30.9000/18.fc32/x86_64/glibc-2.30.9000-18.fc32.x86_64.rpm https://kojipkgs.fedoraproject.org//packages/glibc/2.30.9000/18.fc32/x86_64/glibc-common-2.30.9000-18.fc32.x86_64.rpm https://kojipkgs.fedoraproject.org//packages/glibc/2.30.9000/18.fc32/x86_64/glibc-langpack-en-2.30.9000-18.fc32.x86_64.rpm

4. logout from the VM

5. try to login again
ssh -p 2619 -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null -i /tmp/inventory-cloudjqqtug44/identity root.0.3

Comment 1 Bruno Goncalves 2019-11-19 10:23:49 UTC

I've used standard-test-roles to boot the VM

TEST_DEBUG=1 TEST_SUBJECTS=./Fedora-Rawhide.qcow2 ansible-inventory --inventory=/usr/share/ansible/inventory/standard-inventory-qcow2 --list

Comment 2 Bruno Goncalves 2019-11-19 10:42:56 UTC

This issue has been addressed by an update of openssh. https://bugzilla.redhat.com/show_bug.cgi?id=1771946


If I update openssh to openssh-8.1p1-2.fc32 it works.
