[Pkg-sssd-devel] Bug#1081027: src:sssd: flaky autopkgtest: spawn id exp3 not open

[Andreas Hasenack]

I wrote that test initially, and it has been passing in Ubuntu. Sounds
like it's some difference in the infrastructure.

I tried locally in a debian LXD container, and it passed just fine. Is
it also failing in salsa pipeline runners, or just in the migration by
britney?

The error seems to indicate that "login" died, or wasn't ready:

105s + /usr/bin/expect -f debian/tests/login.exp testuser1
testuser1kerberos testuser1 at EXAMPLE.COM
105s spawn login
105s send: spawn id exp3 not open
105s     while executing
105s "send "$user\r""
105s     (file "debian/tests/login.exp" line 21)
105s autopkgtest [18:34:46]: test ldap-user-group-krb5-auth:
-----------------------]

These timestamps don't seem to indicate when it happened, but when the
log dump happened, right? Otherwise it all happened at 105s basically.

If this failure also happens in salsa, then we can inject some
debugging into the test in the case of failures. I don't know if I
have permissions to trigger a pipeline run in salsa, I'll try with an
MP.
