yum and Python

[yorelchr]

ok, so I've installed urlgrabber:

[root@mediceo6NB leroy]# rpm --force -ivh http://archive.fedoraproject.org/pub...c12.noarch.rpm
Retrieving http://archive.fedoraproject.org/pub...c12.noarch.rpm
Preparing... ########################################### [100%]
1ython-urlgrabber ########################################### [100%]

then

[root@mediceo6NB leroy]# yum check-update
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

No module named pycurl

Please install a package which provides this module, or
verify that the module is installed correctly.

It's possible that the above module doesn't match the
current version of Python, which is:
2.6.2 (r262:71600, Jun 4 2010, 18:28:58)
[GCC 4.4.3 20100127 (Red Hat 4.4.3-4)]

If you cannot solve this problem yourself, please go to
the yum faq at:
http://yum.baseurl.org/wiki/Faq

so I've isntalled the pycurl (just found python-pycurl)

[root@mediceo6NB leroy]# rpm --force -ivh http://archive.fedoraproject.org/pub...c12.x86_64.rpm
Retrieving http://archive.fedoraproject.org/pub...c12.x86_64.rpm
Preparing... ########################################### [100%]
1ython-pycurl ########################################### [100%]

but as I used one of the previous command already typed and replaced by the new url, I've launched it with rpm -ivh instead of rpm -Uvh ... from man rpm I read the diference between the 2 but as I installed a new one, it should also be an upgrade no? or should I do it again with -Uvh? (I'm really sorry for all these stupid questions, but the last time I tried to do by myself led me to this situation !!! )

and then :

[root@mediceo6NB leroy]# yum check-update
Plugin "refresh-packagekit" can't be imported

PS: sorry, I didn't see the added post at the end of your previous message.
It seems that nothing is missing anymore so I can do a full update?
I just type

yum update ?

[PabloTwo]

The "-i" option to rpm command just means "install".
The "-U" option to rpm command means "upgrade existing program or install it if it isn't already installed".
I probably should have been using the "-U" option in all my previous directives, but things still work out OK.

Yes, go for it: yum update

[yorelchr]

ok.

[root@mediceo6NB leroy]# yum update
Plugin "refresh-packagekit" can't be imported
Loaded plugins: presto
Setting up Update Process
No Packages marked for Update

why can't the refresh-packagekit be imported? should I do the previous commands using the -Uvh option instead of -ivh?

[PabloTwo]

I'm not sure what's still needing installing/updating: Plugin "refresh-packagekit" can't be imported
But it must be another python package that needs updating based on the "can't be imported" part.

No, you don't need to re-run those rpm commands again as they worked in the first place.
What is the output of:

rpm -qa | grep -i packagekit

---------- Post added at 01:13 PM ---------- Previous post was at 01:05 PM ----------

OK.. now booted into F12 myself. I think the quick way to resolve this one is:

rpm --nodeps -e PackageKit-yum-plugin

I have every "PackageKit" item removed from my F12 install and only use yum at the command line.

[yorelchr]

ok, I directly did the second command,followed by the first one

[root@mediceo6NB leroy]# rpm --nodeps -e PackageKit-yum-plugin
[root@mediceo6NB leroy]# yum check-update
Loaded plugins: presto
[root@mediceo6NB leroy]# rpm -qa | grep -i packagekit

PackageKit-gstreamer-plugin-0.5.7-2.fc12.x86_64

then again:

[root@mediceo6NB leroy]# yum check-update
Loaded plugins: presto
[root@mediceo6NB leroy]# rpm --nodeps -e PackageKit-yum-plugin
error: package PackageKit-yum-plugin is not installed

strange? do I install one of this?
http://rpm.pbone.net/index.php3/stat....i686.rpm.html

[PabloTwo]

rpm -e presto yum.presto

[root@mediceo6NB leroy]# rpm --nodeps -e PackageKit-yum-plugin
[root@mediceo6NB leroy]# yum check-update
Loaded plugins: presto <== WHAT HAPPENS AFTER here?

The presto plugin won't work now anyway so might as well get rid of it.
Why did you try and uninstall PackageKit-yum-plugin again after you already uninstalled it?

[yorelchr]

hum, I'm lost ... I send you what I've done in the exact way, as it appears on the screen :

[root@mediceo6NB leroy]# yum update

[root@mediceo6NB leroy]# yum check-update
Loaded plugins: presto
[root@mediceo6NB leroy]# rpm --nodeps -e PackageKit-yum-plugin
error: package PackageKit-yum-plugin is not installed

as the first time I did rpm --nodeps -e PackageKit-yum-plugin nothing seemed to happen and as I hadn't done the command you gave before, rpm -qa | grep -i packagekit , I did everything again in the good way.
After that I didn't do anything else. Did I miss something?

PS: nothing happened after "presto"...just few seconds then again appeared the #root..... line

---------- Post added at 09:13 PM ---------- Previous post was at 09:12 PM ----------

I forgot :

[root@mediceo6NB leroy]# rpm -e presto yum.presto
error: package presto is not installed
error: package yum.presto is not installed

[PabloTwo]

The "rpm --nodeps -e PackageKit-yum-plugin" command doesn't print anything to screen without the -v option added. It just erases the package you specify.

So, doing "yum check-update" just gives you a line: "Loaded plugins: presto" and nothing else and then gives a new command prompt line? No other error messages? Strange.
I think you missed doing this one:

rpm -ev presto yum-presto

[yorelchr]

[root@mediceo6NB leroy]# rpm -ev presto yum-presto
error: package presto is not installed

I tried again the yum check-update, but still the same....presto then few seconds and nothing.

As it is for now, is my computer ok for normal use?
I would like to install the program I need for work but before, I want to know if it could cause troubles because I'll have to install a lot of programs before ( swig, MPI, CGN5, HDF5, MED, Zlib, BLAS, Metis, Scotch, PyQt); they should already be installed since I've installed them before the yum crash and all was ok for the installation of my program, but as Python is also needed, maybe now I will have to change some versions or something of this kind....because they won't recognise the new python....dunno....

[PabloTwo]

Well, the way to check if your computer is "ok for normal use" is to just use it and see if anything is broken. I'm still wondering what is the problem with yum though. Do you get anything back from the commands:

yum repolist
yum list kernel

Maybe post the output of:

cat /etc/yum.conf

---------- Post added at 03:59 PM ---------- Previous post was at 03:54 PM ----------

It might be a good idea to comment out the "metadata_expire=7d" line in the /etc/yum.conf file, or just set it to =0 for the time being for testing.
You'll probably need to get yum working so you can get python back fully installed. Since you deleted so much python stuff, anything that depends on it is probably broken right now.

[yorelchr]

here are the results.

then after that I've commented out the "metadata_expire=7d"

should I install package yum.presto and package presto?

And so, I go on with the installation of my program.

[PabloTwo]

OK, good, that all looks OK to me and the repos seem to be working. You seem to already have done a successful "update" as I see you have the last kernel for F12 that was issued.

No, do not re-install presto and yum-presto because they are now useless. The presto delta-rpms repos for F12 are long gone.

Ummm.... wait a minute... you should NOT have "Loaded plugins: presto" if you have removed the presto and yum-presto packages.

---------- Post added at 04:22 PM ---------- Previous post was at 04:19 PM ----------

What does this say:

rpm -qa | grep presto

[yorelchr]

it's really confusing for me...I shouldn't have presto no??? just when I thought I was starting to understand few things :-(
here's the result:

[root@mediceo6NB leroy]# rpm -qa | grep presto
yum-presto-0.6.2-1.fc12.noarch

[PabloTwo]

Well, now you should be able to do:

yum erase yum-presto

No, you shouldn't have the presto plugin for yum... as I explained above, it's now useless.

[yorelchr]

what I don't understand is that presto seemed not being in my pc, but when asking..it is...so strange to me...

I mean that, previously I had :

[root@mediceo6NB leroy]# rpm -ev presto yum-presto
error: package presto is not installed

then

[root@mediceo6NB leroy]# rpm -qa | grep presto
yum-presto-0.6.2-1.fc12.noarch

that's a bit complicated for me to understand ....

anyway, I erased :

[root@mediceo6NB leroy]# yum erase yum-presto
