Broken yum, curl and multilib problems

[ToughNode]

Sorry in advance for the blatant stupidly!
I recently installed fedora19 on my Asus N55sf after having not used Fedora for a while. I use bumblebee and bbswitch as it has Nvidia Optimus. Occasionally it doesn't boot into the desktop but hangs before the login prompt (separate issue). Last time this happened I swapped into a virtual terminal and decided to run a yum update in case the problem that caused the failure of X had been caused by a bug in a package which since had been updated. Unfortunately while running the update, my computer rebooted unexpectedly. I then successfully rebooted into the desktop and ran the update again but encountered errors about unfinished transactions. I followed the suggested instructions to complete the transactions but was left with messages when running yum update about protected packages and mulitilb conflicts. I ran yum distro-sync which seemed to stop yum update complaining so much. After googling the error I stupidly decided to remove the i686 versions of nss and nss-softokn using

sudo rpm --nodeps -e nss.i686 nss-softokn.i686

to see if this resolved the apparent conflicts! Stupid idea as this broke curl which clearly relies on nss and/or nss-softokn. As I couldn't find a local cached copy of these packages to use "yum localinstall" I downloaded the two packages from an http mirror and installed them as follows:

sudo rpm -Uvh nss-3.15.2-1.fc19.i686.rpm
sudo rpm -Uvh nss-softokn-3.15.2-1.fc19.i686.rpm

But yum and curl are still broken. I wonder whether Curl which is used by Yum is looking for the NSS binary in the wrong place? Perhaps dynamically linked to the wrong version of nss or nss-softokn? On Gentoo I'd probably run their revdep-rebuild tool which might fix the dynamic linking problem.

My current "yum check" output is:

Error: check all

yum distro-sync yields an unending string of mirrors not found, as does yum update. So, basically I can't update or install any software or probably use any software that uses curl.

Could I manually diagnose/fix the links to the right binaries or have I irreparably broken my system by venturing outside the relative safety of yum?

Thanks for any suggestions you may have.

UPDATE: for some reason yum is now working! not sure why.
yum still complains with the following (probably not the end of the world though):

Warning: RPMDB altered outside of yum.

UPDATE 2:
So I think I have solved the yum errors. I ran:
yum clean all
yum distro-sync
yum update

Hi All,

I seem to have a similar issue, I tried to run

sudo yum update

and receive the following error:

--> Finished Dependency Resolution
Error:  Multilib version problems found. This often means that the root
       cause is something else and multilib version checking is just
       pointing out that there is a problem. Eg.:
       
         1. You have an upgrade for nspr which is missing some
            dependency that another package requires. Yum is trying to
            solve this by installing an older version of nspr of the
            different architecture. If you exclude the bad architecture
            yum will tell you what the root cause is (which package
            requires what). You can try redoing the upgrade with
            --exclude nspr.otherarch ... this should give you an error
            message showing the root cause of the problem.
       
         2. You have multiple architectures of nspr installed, but
            yum can only see an upgrade for one of those architectures.
            If you don't want/need both architectures anymore then you
            can remove the one with the missing update and everything
            will work.
       
         3. You have duplicate versions of nspr installed already.
            You can use "yum check" to get yum show these errors.
       
       ...you can also use --setopt=protected_multilib=false to remove
       this checking, however this is almost never the correct thing to
       do as something else is very likely to go wrong (often causing
       much more problems).
       
       Protected multilib versions: nspr-4.10.1-1.fc19.i686 != nspr-4.10.0-3.fc19.x86_64

I was able to complete both

sudo yum clean all

as well as

sudo yum dystro sync

, but as soon as I try to update, I fail again. any help much appreciated.

Update: I ran

sudo yum update nspr

and got an error that nspr was up to date. I removed nspr.i686, and was sucessfully able to run yum update. After, I ran yum update nspr and no errors. I think everything is all good?
