** Changed in: procps (Ubuntu T-series)
       Status: Confirmed => Fix Committed

** Tags added: verification-done-raring

** Description changed:

  [SRU justification]
  In a container, the procps package fails to upgrade because sysctl will fail 
when it can't write to certain keys.  Since the procps has just been SRUed, 
this means anyone running Ubuntu in a container (12.04 or later) will have 
upgrade failures because of the procps upstart job failing to start.
  
  [Test case]
  1. Set up precise in an lxc container.
  2. Apply updates from the -updates pocket.
  3. Observe that the procps package fails to install.
  4. Enable -proposed.
  5. Install the procps package from -proposed.
  6. Observe that the package upgrades successfully.
  
  [Regression potential]
- This patch changes the behavior of the sysctl program and causes permission 
errors to be non-fatal.  Anything relying on the current behavior (e.g., when 
sysctl is run by a non-root user) will regress as a result of this change, but 
it's not obvious why anything would rely on this since sysctl is not meant to 
be invoked by non-root users.

it's not obvious why anything would rely on this since sysctl is not meant to 
be invoked by non-root users.  It *also* means that sysctl settings that were 
previously not applied due to errors earlier in the sysctl config will now be 
applied, resulting in unexpected behavior on some systems due to configured 
settings now being applied.

  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@xxxxxx:~# apt-get  upgrade
  Reading package lists... Done
  Building dependency tree
  Reading state information... Done
  0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded.
  1 not fully installed or removed.
  After this operation, 0 B of additional disk space will be used.
  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.default.rp_filter = 1
  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@xxxxx:~# service procps start
  start: Job failed to start
