[Bug 1157643] Re: procps fail to start

[Sidnei da Silva]

So if I understand the whole context, procps start has always been
broken in lxc (and maybe openvz too?) because the apparmor profile
restricts writes to the kernel namespace. When called from upstart the
failure to start is ignored. dpkg is not as forgiving, so trying to
upgrade the package blows up because the service start step blows up.
This started happening when the update to procps landed in precise-
updates.

"<slangasek> sidnei: workarounds are possible (e.g., editing /usr/sbin
/policy-rc.d to ignore requests for procps; or editing the config file
in the container to comment out the problematic bits).  A proper fix is
going to take a bit."

  I have a VPS that i upgraded from Ubuntu 10.10 to 11.10 and then to 12.04.2 LTS.
  But something is wrong and now i can't upgrade procps. I get the following output,

  root at xxxxxx:~# apt-get  upgrade
  Reading package lists... Done

  Do you want to continue [Y/n]?
  Setting up procps (1:3.2.8-11ubuntu6) ...
  start: Job failed to start
  invoke-rc.d: initscript procps, action "start" failed.
  dpkg: error processing procps (--configure):
   subprocess installed post-installation script returned error exit status 1
  Errors were encountered while processing:
   procps
  E: Sub-process /usr/bin/dpkg returned an error code (1)

  the /var/log/upstart/procps.log says,

  kernel.printk = 4 4 1 7
  net.ipv6.conf.all.use_tempaddr = 2
  net.ipv6.conf.default.use_tempaddr = 2
  error: permission denied on key 'kernel.kptr_restrict'

  net.ipv4.conf.all.rp_filter = 1
  net.ipv4.tcp_syncookies = 1
  vm.mmap_min_addr = 65536

  And the output when i try to start procps is just the following,

  root at xxxxx:~# service procps start
  start: Job failed to start
