whenever I do a yum , it tries all the mirrors but fails in all of them
some thing like

Setting up and reading Presto delta metadata
Processing delta metadata
Package(s) data still to download: 6.0 M
http://download.fedoraproject.org/pu...fc14.i686.rpm: [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.

and finally
Error Downloading Packages

Hi there,

I have seen this error before. I found that I have configured a wrong route in my linux system and that is the reason I was getting this error. Check routing table on your system. You can check it using the following command:

route

If you think that there is a route which is not correct, just delete that route. If you don't know how to do that then paste your routing table here or type "man route" without quotes at console to get information on how to delete a route

Also check if you have got your system's host name configured in /etc/hosts.

i think my route is ok
this is route output
[root@localhost ~]# route
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref Use Iface
10.117.172.0 * 255.255.255.0 U 1 0 0 eth0
default 10.117.172.3 0.0.0.0 UG 0 0 0 eth0

problem is
Error Downloading Packages:
libstdc++-devel-4.5.1-4.fc14.i686: failure: Packages/libstdc++-devel-4.5.1-4.fc14.i686.rpm from fedora: [Errno 256] No more mirrors to try.
gcc-c++-4.5.1-4.fc14.i686: failure: Packages/gcc-c++-4.5.1-4.fc14.i686.rpm from fedora: [Errno 256] No more mirrors to try.

Have a look at my posting in this thread: http://www.linuxquestions.org/questi...ration-881907/

If this does not work let us know how you are setting up repository are you using online repo or you have created your own repo. Paste the repo configuration files here.

well that mirror works
h??p://download.fedoraproject.org/pub/fedora/linux/releases/14/Everything/i386/os/Packages

and you start with a python error
Question
Did you by chance install a DIFFERENT version of python ,than the one fedora has in the fedora repo ?
if yes that is the cause
if not then


are you behind a router
ff can auto setup for it but sometimes not yum


but the very first thing i do for any ( almost any) um error is to clear the cache

I did what John suggested
now yum does not work at all
example from the last command


yum update
Loaded plugins: langpacks, presto, refresh-packagekit
Adding en_US to language list
http://linuxdownload.adobe.com/linux...ta/repomd.xml: [Errno 14] PYCURL ERROR 6 - ""
Trying other mirror.
Error: Cannot retrieve repository metadata (repomd.xml) for repository: adobe-linux-i386. Please verify its path and try again

disable the adobe repo and try again

?????
?????
then please answer the two questions i posted BEFORE cleaning yumn's cache !

to quote-------
well did you install a different version of python ?

and are you behind a router ?

also this
that is a VERY VERY well known issue with ADOBE
there servers go offline ALL the time
just turn that one off
