Has anyone else run into this? I've never before run into this
problem, not any version of Server or Workstation. Just cloud, and
I've run into it several times in just a few days.
I'm using public-key authentication to ssh into a Fedora 23 Cloud
Atomic ISO installation upgraded to 23.29. This works most of the
time, until it doesn't and then I always get this.
[chris@f23m ~]$ ssh chris(a)10.0.0.15
PTY allocation request failed on channel 0
If I happen to have an existing login available, even if I restart
sshd the problem isn't fixed. The only fix I've found so far is a
reboot which is more than a bit disruptive. Any ideas?
In the journal host side, it records a bunch of audit stuff, but three
lines that seem particularly relevant yet not illuminating:
Dec 12 12:37:10 f23a.localdomain audit[1]: USER_AVC pid=1 uid=0
auid=4294967295 ses=4294967295 subj=system_u:system_r:init_t:s0
msg='Unknown permission start for class system
exe="/usr/lib/systemd/systemd" sauid=0 hostname=? addr=? terminal=?'
[snip]

I'd file a bug but I don't even know what to file it against. The full
journal output is here:
