The common fix is to delete the rpm databases and run rebuilddb, like<\/p>\n

# yum clean all
\n# rm -f \/var\/lib\/rpm\/__db*
\n# rpm –rebuilddb
\n# yum update<\/strong><\/span><\/p><\/blockquote>\n

However, in case of a VPS, yum may still not work with rebuilding rpm database and you have to try create a \/dev\/urandom device. Login to your VPS and execute<\/p>\n

# rm \/dev\/urandom
\n# mknod -m 644 \/dev\/urandom c 1 9<\/strong><\/span><\/p><\/blockquote>\n

The problem may reoccur on a VPS reboot so to fix the problem permanently, login to Hardware Node and execute:<\/p>\n

# vzctl stop VEID
\n# mknod –mode 644 \/vz\/private\/VEID\/fs\/root\/dev\/urandom c 1 9
\n# vzctl start VEID<\/strong><\/span><\/p><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
