[Launchpad Bug Tracker <1746947@xxxxxxxxxxxxxxxxxx>]

This bug was fixed in the package nss - 2:3.35-2ubuntu2

---------------
nss (2:3.35-2ubuntu2) bionic; urgency=medium

  * d/p/lp1746947-revert-switch-default-to-sql.patch: the switch of the
    default is still causing too much issues in consumers of nss.
    So until resolved revert the switched default (LP: #1746947)

nss (2:3.35-2ubuntu1) bionic; urgency=medium

  * Merge with Debian unstable. Remaining changes:
    - When building with -O3, build with -Wno-error=maybe-uninitialized.
  * Added Changes:
    - d/libnss3.links: make freebl3 available as library (LP: #1744328)
      + d/control: add dh-exec to Build-Depends
      + d/rules: make mkdir tolerate debian/tmp existing (due to dh-exec)

nss (2:3.35-2) unstable; urgency=medium

  * nss/lib/freebl/Makefile: Build Hacl_Poly1305_64.o on arm64.

nss (2:3.35-1) unstable; urgency=medium

  * New upstream release.

nss (2:3.34.1-1) unstable; urgency=medium

  * New upstream release.

Title:
  failing autopkgtest due to password issue by nss

Status in freeipa package in Ubuntu:
  New
Status in nss package in Ubuntu:
  Fix Released

Bug description:
  Hi,
  I was failed by autopkgtests of freeipa, but not the old "ip route output changed" case.
  Like: https://objectstorage.prodstack4-5.canonical.com/v1/AUTH_77e2ada1e7a84929a74ba3b87153c0ac/autopkgtest-bionic/bionic/amd64/f/freeipa/20180201_161632_c9091@/log.gz

  It essentially does this and fails:
  $ apt install freeipa-server freeipa-server-dns freeipa-server-trust-ad freeipa-common freeipa-client freeipa-admintools freeipa-tests python-ipaclient python-ipalib python-ipaserver python-ipatests

  Containers:
  Bionic-as-is: installs ok
  Bionic-Proposed: installs ok

  In LP Infra:
  dpkg: error processing package freeipa-client (--configure):
   installed freeipa-client package post-installation script subprocess returned error exit status 1

  Use Pinning to get the autopkgtest style:
  # cat /etc/apt/preferences.d/nssonlyproposed
  Package: *
  Pin: release a=bionic
  Pin-Priority: 1001
  Package: libnss3 libnss3-tools libnss3-dev libnss3-dbg
  Pin: release a=bionic-proposed
  Pin-Priority: 1002
  Bionic-nss-only-from-Proposed: TRIGGERS the issue

  freeipa-client is in the postinst calling this:
  python2 -c 'from ipapython.certdb import update_ipa_nssdb; update_ipa_nssdb()'
  Traceback (most recent call last):
    File "<string>", line 1, in <module>
    File "/usr/lib/python2.7/dist-packages/ipapython/certdb.py", line 64, in update_ipa_nssdb
      create_ipa_nssdb()
    File "/usr/lib/python2.7/dist-packages/ipapython/certdb.py", line 53, in create_ipa_nssdb
      db.create_db(pwdfile)
    File "/usr/lib/python2.7/dist-packages/ipapython/certdb.py", line 149, in create_db
      self.run_certutil(["-N", "-f", password_filename])
    File "/usr/lib/python2.7/dist-packages/ipapython/certdb.py", line 142, in run_certutil
      return ipautil.run(new_args, stdin, **kwargs)
    File "/usr/lib/python2.7/dist-packages/ipapython/ipautil.py", line 515, in run
      raise CalledProcessError(p.returncode, arg_string, str(output))
  subprocess.CalledProcessError: Command '/usr/bin/certutil -d /etc/ipa/nssdb -N -f /etc/ipa/nssdb/pwdfile.txt' returned non-zero exit status 255

  
  That is - if called alone complaining about the passwd:
  # /usr/bin/certutil -d /etc/ipa/nssdb -N -f /etc/ipa/nssdb/pwdfile.txt
  Invalid password.
  certutil: Could not set password for the slot: SEC_ERROR_BAD_PASSWORD: The security password entered is incorrect.

  
  Note that there is a related freeipa fix in later versions:
     freeipa (4.6.2-4) unstable; urgency=medium                                       
                                                                                      
       * client.postinst: Migrate from old nssdb only if it exists.

  And since that change freeipa has:
  if [ -f /etc/ipa/nssdb/cert8.db ]; then
  around the call.

  It also changed the import slightly - now the python being:

  python2 -c 'from ipaclient.install.client import update_ipa_nssdb;
  update_ipa_nssdb()'

  That in the "all-proposed" case with the cert8.db file copied over is still failing but differently:
  /usr/bin/certutil -d /etc/ipa/nssdb -L -f /etc/ipa/nssdb/pwdfile.txt
  certutil: function failed: SEC_ERROR_BAD_DATABASE: security library: bad database.

  The merge of nss was a minor bump 3.34->3.35
  Also this is the nss version from Debian with the freeipa version from Debian. They seem to work together there.

  I don't fully understand it yet - so filing this bug for a discussion.
  I need the help of tjaalton who did the freeipa changes - maybe he knows what is going on.

  Do we have to:
  - rebuild freeipa against newer nss?
  - just mark something as bad test
  - something completely else?
