Shriek! After latest Portage ... can't log in!

The latest "routine" Portage updates update PAM but apparently don't cause the recompile of things that may depend on it. With the result that I narrowly avoided having (pure dumb-luck, really) a system that I could not log-in to!

Fell into this trap as well... avoided on one machine (x86), but pure dumb luck as well, I ran an emerge -De world just after the sync that would have updated pam, so was lucky.

On the other machine (amd64), the pam upgrade was done after the emerge -De world, and as nothing was picked up by revdep-rebuild, I thought I was ok, until kdm wouldn't let me log in!

Luckily, I had a spare machine to surf the net, and so find the error! The pam upgrade guide says nothing about re-emerging kdm, kcheckpass, etc, which O hope will allow me to log in again... I miss mythtv!

EDITED orignal post

See this [solved] Messed up Pam upgrade, now can't su and.... on what to do and how to do it.

Sounds like a nasty bug if 3 or 4 of you have hit it.

Fell into the same trap with my girlfriends machine. After updating pam, I was only able to login on a perchance basis (weird). Reemerging shadow fixed it, its recompiling the other packages depending on pam right now. A very nasty one that can totally screw a perfectly stable system.

I followed the advice of running qdepends -Q pam and re-emerging every package that it spoke of.

Then I did revdep-rebuild -X and let it run a couple of times through.

Still, any new X-session was crapping-out.

"Well, there's only one way to do this," I murmured, and switched to root and did killall kdm. Then, after doing cat /etc/inittab to find the proper command, I restarted KDM with /etc/X11/startDM.sh ... and prayed.

Fortunately, when the graphical login screen came up again, it all worked.

The contents of /var/log/messages seems fairly quiet now...

Pam's a bitch .

I never, ever let an upgrade touch pam unless I have a day spare.

Just lock it using package.mask until you get a dependacy needing an upgrade. Then back everything up make a quickpkg on pam and have liveCD handy.

Always check out this forum before diving in , avoid being the first.

Gentree unfortunatly that doest work :cry:

You can never tell if nobody is having probs of if your the first. Of course if you do find anything about the package your concerned about then wait a week or so

Even that soesnt always work I was going wait a week or 2 for linux-headers-2.6.23 and gpm prob but ended up accident installing it. Gpm wont build without the patch but the current version still runs so it isnt a run time requirement.
