Installing the python-hashlib package help to add SHA256 capabilities. Recently, one of the customers had a problem with yum error performing checksum while installing a package using the yum. The version of the SHA module that ships with CentOS 5.3 doesn’t support sha256, that is why we get the checksum error. Python 2.6 uses hashlib to perform checksums whereas Python 2.4 uses the SHA module to perform checksums. Now, let’s see the major reasons for this error and how our Support Engineers fix this error by different methods. Let, see how our support engineers help to fix this problem by various methods.ĭifferent methods to fix yum error performing checksum!Īt Bobcares, where we have more than a decade of expertise in managing servers, we see many customers face problems with the yum error performing checksum. This happens due to the necessary libraries not available for yum to calculate the new checksum correctly. In simple words, from the error, it’s clear that the yum is unable to calculate the sha256 checksum. Createrepo is a program that creates a repomd (xml-based rpm metadata) repository from a set of RPMs. The error has been identified when yum update on a Centos5 or RHEL5 box, using RPMs from a repository on a CentOS6 or RHEL6 server (or anywhere else with a more modern createrepo available). Often the error happens when installing packages that do not match the server architecture. Generally, yum error performing checksum occurs when we install or update a new package using yum. In other words, when the file goes corrupt, the checksum may not match. YUM is a program that manages installation, updates, and removal for Red Hat package manager (RPM) systems.Ī checksum is a small-sized datum assigned to any file for the purpose of detecting errors. Yum stands for Yellowdog Updater, Modified. We’ll also see how our Support Engineers fix the error performing checksum. Today, let’s have a quick look at reasons for the occurrence of this error. The error is usually generated when the checksum algorithm specified in the repository file will not support the yum version.Īt Bobcares, we often get requests to fix yum errors, as a part of our Server Management Services. Occasionally while installing a package or updating using YUM command ends up in this error. Are you struggling with YUM error performing checksum?
