Python issues in Yum

[Hunkah]

Hello everyone, I somehow listened to an online walk-through to upgrade to the next big version of Fedora! The day I did that, I haven't been able to log in to graphical mode. It keeps rebooting. So I have been daily logging in through the command line, and yum updating, to see if it will fix the problem. Now, I can't even yum update!

Can someone help me? Or help me downgrade back to F11?

Thanks.

Here is what happens:

# yum -y --disablerepo=* --enablerepo=rawhide update --skip-broken
There was a problem importing one of the Python modules
required to run yum. The error leading to this problem was:

   /usr/lib/libcurl.so.4: undefined symbol: libssh2_knownhost_init

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, Jul 30 2009, 17:09:09)
[GCC 4.4.1 20090725 (Red Hat 4.4.1-3)]

If you cannot solve this problem yourself, please go to
the yum faq at:

Keeps rebooting or does it keep going back to the log in screen?

I have F12 installed to an Acer Aspire One and after updating today I get the same error message:

/usr/lib/libcurl.so.4: undefined symbol: libssh2_knownhost_init

dont have a reboot problem but neither epiphany or firefox run now and crash on start up.

Guess Xfce testing is out of the question now unless I can figure out how to back out of the recent updates or satisfy the missing dependency causing the break. This is the first real stumbling block for me so far with F12.

The dependancy will probably show up in the next couple of days.

Sorry, Log in screen. It used to reboot or lock up, but after about a week of doing the "yum update" it now only goes back to the log in screen.

Use CTRL/ALT/F2 to get to a virtual terminal. Log in as root. Type

yum downgrade xorg-x11-server-Xorg

Reboot. This worked for me. It solved the problem that you are describing.

You've probably rebooted by now Ryptyde? I tried yum updating my F12 system last night and got the same error. A reboot fixed things right up.

I would love to do this, but we are back to the original issue... I can't "yum" anything!

Yum is broken.

OK, I went to that link at the bottom
http://wiki.linux.duke.edu/YumFaq

...and followed what it said, and this is what I got.

Only I can't make sense of it.

Umm... Yeah. Forget I said anything. Sometimes I get lost along the way. I think I stumbled in here by accident

Hey you're not getting off that easy pull up a seat and stay a while.

I have managed to fix the yum issue and also my web browser problem.

Downloaded and installed libcurl-7.19.6-8.fc12.i686.rpm libssh2-1.2-2.fc12.i686.rpm from RPMFIND to fix yum and then as a quick fix for the browsers set selinux to permissive.

Now I'm back in the game and hoping not to get sidelined soon.

a couple of more smilies and you might think a "bee" stung me.

Frig, I was going along fine, but now I am stuck again.

# rpm -ivh libssh2-1.2-2.fc12.i686.rpm

        libssl.so.10 is needed by libssh2-1.2-2.fc12.i686

So to get them, I needed openssl-1.0.0-0.7.beta3.fc12.i686.rpm

When I went to install it, I got.

So I am guessing this is what they mean by dependency hell? I have heard the term, but never knew what it meant.

libcrypto.so.10 is needed by libssh2-1.2-2.fc12.i686
libssl.so.10 is needed by libssh2-1.2-2.fc12.i686

should be in rawhide repo but i cannot see libssl.so.8 in rawhide

So am I screwed at this point then? I can't log into the GUI, I am unable to YUM I can't update YUM and I have no way to downgrade either.

Am I looking at a reinstall of F11?

That may be the way to go. If you "upgraded" from F11 to rawhide it would definitely guarantee difficulties more so than say going from the current stable release to the next stable one. I installed the first Live Alpha of F12 to a usb device then installed to hdd on a Acer Aspire One.

If you have data that you want to save and choose to reinstall use a livecd/usb to get the data off your drive. Either reinstall F11 or grab the latest F12 live image and see how it works before installing.
