[Bug 1792231] Re: openssh-client: 'DISPLAY "(null)" invalid; disabling X11 forwarding'
14.04 has transitioned off Standard Support to Extended Security Maintenance (https://ubuntu.com/blog/ubuntu-14-04-trusty-tahr) as of April 2019. Under ESM the focus for changes is more on security vulnerabilities in non-desktop packages. Since this issue sounds to be more on the cosmetic side, I don't think this fits in the ESM update policies. But, I'll attach the patch for future reference. ** Patch added: "avoid_ugly_display_null_invalid_with_x11.patch" https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1792231/+attachment/5482868/+files/avoid_ugly_display_null_invalid_with_x11.patch ** Changed in: openssh (Ubuntu Trusty) Status: Triaged => Won't Fix ** Tags removed: server-next -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1792231 Title: openssh-client: 'DISPLAY "(null)" invalid; disabling X11 forwarding' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1792231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Ok, some magic affects containers int hat case (even ssh to the LXD and then re-ssh to itelf would not work). But in a KVM guest I could recreate it. $ ssh -X ubuntu@localhost uname -a ubuntu@localhost's password: DISPLAY "(null)" invalid; disabling X11 forwarding Linux t1 3.13.0-157-generic #207-Ubuntu SMP Mon Aug 20 16:44:59 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1792231 Title: openssh-client: 'DISPLAY "(null)" invalid; disabling X11 forwarding' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1792231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

I wanted to check if other releases are affected as well, but it was interesting as it didn't show up even on a Trusty container ssh'ing to itself. ubuntu@t:~$ unset DISPLAY ; ssh -X ubuntu@localhost 'dpkg -l openssh-client | grep ii' ubuntu@localhost's password: ii openssh-client 1:7.2p2-4ubuntu2.4 amd64secure shell (SSH) client, for secure access to remote machines No issue, to be seen. @Santiago - do you know what the secret ingredient to trigger the bug might be? ** Bug watch added: Debian Bug tracker #908652 https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=908652 ** Also affects: openssh (Debian) via https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=908652 Importance: Unknown Status: Unknown -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1792231 Title: openssh-client: 'DISPLAY "(null)" invalid; disabling X11 forwarding' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1792231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Broken since security update on Thu, 05 May 2016 Fixed in Debian in openssh/1:6.7p1-5+deb8u7 Per the Debian bug they were affected as well re-using our CVE fixes in Debian. I think we can use the changes taken for openssh/1:6.7p1-5+deb8u7 when they are visible. Right now I don't see more yet, so it waits to be released there. The fix looks rather trivial (thanks for linking) and we should take a look at this soon. ** Changed in: openssh (Ubuntu) Status: New => Triaged ** Tags added: server-next -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1792231 Title: openssh-client: 'DISPLAY "(null)" invalid; disabling X11 forwarding' To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/openssh/+bug/1792231/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
