[Bug 1690807] [NEW] getaddrinfo failed: Name or service not known

[gopalakrishna]

Public bug reported:


 We had face the issue of "getaddrinfo failed: Name or service not
known". Today I have try to upgrade "libc6" version upgraded. We have
checked libc6 version before upgrading (2.19-0ubuntu6.11). After the
libc6 version upgrade  process we "rebooted" the instance, but still
it's showing the same version libc6(2.19-0ubuntu6.11).

Before upgrading the version,

Distributor ID:	Ubuntu
Description:	Ubuntu 14.04.1 LTS
Release:	14.04
Codename:	trusty

root at test1:~# dpkg -l | grep libc6
ii  libc6:amd64                      2.19-0ubuntu6.11                                     amd64        Embedded GNU C Library: Shared libraries
ii  libc6-dev:amd64                  2.19-0ubuntu6.11                                     amd64        Embedded GNU C Library: Development Libraries and Header Files

After upgraded the version we rebooted the instance and checked,

root at test1:~# uptime
 05:49:28 up 7 min,  1 user,  load average: 0.00, 0.05, 0.05

root at test1:~# dpkg -l | grep libc6
ii  libc6:amd64                      2.19-0ubuntu6.11                                     amd64        Embedded GNU C Library: Shared libraries
ii  libc6-dev:amd64                  2.19-0ubuntu6.11                                     amd64        Embedded GNU C Library: Development Libraries and Header Files

We again try to upgrade the version, It shows "libc6 is already the
newest version".
