Hi Guys,

This is Maheswar,Since few days i could not able to update or install any package/RPM in CentOS6.4 through YUM.

When i execute the yum clean all or yum update it is throwing an error.

except KeyboardInterrupt, e: kind of error.

Please find the attached yum.conf file and /usr/bin/yum file and CentOS-Base.repo file under /etc/yum.repos.d/

Appreciate the help.

Thanks & Regards,

# CentOS-Base.repo

# The mirror system uses the connecting IP address of the client and the
# update status of each mirror to pick mirrors that are updated to and
# geographically close to the client. You should use this for CentOS updates
# unless you are manually picking other mirrors.
#
# If the mirrorlist= does not work for you, as a fall back you can try the
# remarked out baseurl= line instead.

# It is esp. important, to have correct metadata, for distributions like

uncomment baseurl in all.
yum clean all
check if its working and if you are connected to internet.

Hi SAbhi,

Thanks for replying to my post.

I uncommented the baseurl.

And checked in the browser and ping to the url on centos, i got the reply.

And then tried yum clean all and getting the below error.

[root@localhost clamav]# yum clean all
File "/usr/bin/yum", line 30
except KeyboardInterrupt, e:
^
SyntaxError: invalid syntax

Thanks

Mahesh

oh this gave me a lesson yum is written in python, so i got this url on the forum check if this is of any help:

Hi,

Still getting same error.

Hi,

Thanks for posting the link and with that did the below changes

Did some chages in /usr/bin/yum

#!/usr/bin/python
import sys
try:
import yum
except ImportError:
print >> sys.stderr, """\

#sys.exit(0)
except KeyboardInterrupt, e:
print("\n\nExiting on user cancel.", file=sys.stderr)
sys.exit(0)"""

then executing yum clean all , immediately it is exiting from the command and showing the
[root@localhost bin]# yum clean all
[root@localhost bin]#

Plz let me know.

Thanks,
Mahesh

what was changed ? just mention what you changed,
yum clean all is not required after that.. since the change is made outside of yum dir..
well try running some install or query and see what it says now..
sorry but this is new error for me so i am not so sure.. i would try best to help though.

it looks like what they told is to change the version python was using in shebang.
