During yum installing , we get the following messages

Error: Multilib version problems found. This often means that the root cause is something else and multilib version checking is just pointing out that there is a problem. Eg.: Protected multilib versions: nss-3.19.1-18.el7.i686 != nss-3.36.0-5.el7_5.x86_64 Error: Protected multilib versions: nspr-4.10.8-2.el7_1.i686 != nspr-4.19.0-1.el7_5.x86_64 Error: Protected multilib versions: nss-util-3.19.1-4.el7_1.i686 != nss-util-3.36.0-1.el7_5.x86_64 Error: Protected multilib versions: nss-softokn-3.16.2.3-13.el7_1.i686 != nss-softokn-3.36.0-5.el7_5.x86_64

what is the meaning of - protected multilib versions

how to resolve this situation?

  • An you also post the output of ‘rpm -q nss nspr nss-util nss-softokn’? I suspect you have an incomplete transaction that left you with multiple copies of the same rpm and arch. Commented Jul 31, 2019 at 20:11

yum multilib makes sure that you install the exact same version of the same program in 32bit and 64bit flavor.

Here yum warns you that he cannot install both

  • nss-3.19.1-18.el7.i686
  • nss-3.36.0-5.el7_5.x86_64

on the same system because they don't have the exact same version number.

To solve this you have multiple options:

  • investigate if you really need to install the 32bit versions of the same program on your 64bit system
  • if you really need those 32bit versions; make sure yum has access to the exact same version numbers for each pair.
  • you might need to help yum a bit because he will always select the very last version avaible for each package to install, so you might need to specify some version numbers manualy.

  • first thank you so much for the really great answer WOW , let me ask you something , since our OS is --> 3.10.0-327.el7.x86_64 , then its logical that we need to remove any rpm of 32bit ( i686 ) , am I right ? Commented Jul 30, 2019 at 11:13
  • "remove ANY" seems a bit dangerous. The question here is rather: why is yum proposing to install nss 32bit while nss64bit is present? I don't really know what nss does, but if it's not crucial you can try removing all nss*i586 rpms from your system. Commented Jul 30, 2019 at 11:27
  • so please correct me if I am wrong , the best solution is to fit the rpm's version that belong to 32 bit to 64bit , is it right? ( for example nss-3.36.0-5.el-18.el7.i686 == nss-3.36.0-5.el7_5.x86_64 Commented Jul 30, 2019 at 12:35
  • yes, that is what multilib tries to do (but probably multilib not only wants the same version numbers but also the same release numbers: 5.el-18 != el_5) Commented Jul 30, 2019 at 12:39
