yum gives illegal instruction error

Latest response

Approximately a week ago two of our servers started giving the error illegal instruction when we run yum update. Even after a yum clean all the error still persists. Has anyone seen this error or have a fix for it?

William,

Can you post the command you are running and the exact error you are receiving? Which version of RHEL is this occuring on? Are you using Satellite/internal repositories or connecting to public yum repositories?

Here is the output of the yum command:

[root@acadtest ~]# yum update Loaded plugins: product-id, rhnplugin, search-disabled-repos, subscription-manager This system is receiving updates from RHN Classic or RHN Satellite. Setting up Update Process Illegal instruction

We are not using satellite but registered the system as we have to date using the rhn_register command from the command line. This is on rhel 6 as are the other two servers that are seeing the same issue. We have other servers that we will start patching once an internal change freeze is over in two days and hope that we do not see the same issues. This problem was or is linked to another issue we are having with the classic subscription management portal where errata and patches would not show up in the portal but would using yum. This other case is CASE 01591205.

This is the output for the final part of a very long report from yum... Commands issued:

]# sed -i 's/enabled=1/enabled=0/g' /etc/yum/pluginconf.d/product-id.conf; sed -i 's/enabled=1/enabled=0/g' /etc/yum/pluginconf.d/subscription-manager.conf; sed -i 's/enabled = 0/enabled = 1/g' /etc/yum/pluginconf.d/rhnplugin.conf

]# export URLGRABBER_DEBUG=1

]# yum clean all

]# yum repolist -v

Output from right before and including the error:

Hey guys having the same problem here. Was there any resolution here? Select RHEL 6.x client registered to local RHN satellite server get "Illegal instruction" error and no yum updates take place. Re-registering and clearing /var/cache/yum does not help.

Ok so here is the solution: I noticed in /var/log/messages:

kernel: yum[3574] trap invalid opcode ip:7f29dd2ead60 sp:7fff439fe238 error:0 in libfreeblpriv3.so[7f29dd298000+72000]

I checked to see what RPM that library (libfreeblpriv3.so) belongs to, which is nss-softokn-freebl. I manually downloaded the latest RPM from RHN, did an manual update (rpm -Uvh nss-softokn-freebl-3.14.3-23.3.el6_8.x86_64.rpm) and now I can run yum updates again.

William,

Could you try Jose De la Rosa's solution? So first check for the error message, and if you find the messages install the latest nss-softokn-freebl rpm.

Success,

Jan Gerrit Kootstra
