YUM fails in clean CentOS 7 install, Exiting on user cancel

If you are installing CentOS 7, you might get an issue with yum update exiting, when it starts downloading packages with the message  Exiting on user cancel even though you haven’t pressed any key, or did anything else that might have cancelled the process.

This seems to be a known bug on Red Hat Enterprise Linux / CentOS 7.1, but it happened on version 7.0.1406 for me.

https://bugzilla.redhat.com/show_bug.cgi?id=1091740

[root@CentOS70x86-001 ~]# cat /etc/redhat-release
CentOS Linux release 7.0.1406 (Core)

After running yum update it would connect to repository any resolve all the dependencies, and list all the packages that need to be updated, but once you would confirm the download, it would initiate download of packages, and then failed with the message indicating that the process was interrupted from keyboard.

Exiting on user cancel

After running bash -c 'yum clean metadata && yum upgrade' as suggested on CentOS forums, yum has downloaded all the packages, and upgraded to latest CentOS version

[root@CentOS70x86-001 ~]# cat /etc/redhat-release
CentOS Linux release 7.2.1511 (Core)

Alternate solution

Another possible solution, to this might be to edit /usr/lib/python2.7/site-packages/urlgrabber/grabber.py file, and change the line number 1510 as below:

Change “elif errcode in (42, 55, 56):” to “elif errcode == 42:”
