pam-login (is blocking sys-apps/shadow-4.0.15-r2)

Published on June 8th, 2006 in Gentoo

After doing an “emerge –sync && emerge -up world” on my Gentoo box, the following error appeared and wouldn’t let me update my system: “sys-apps/pam-login (is blocking sys-apps/shadow-4.0.14-r2)”

So I searched the internet and tried a few things and found this solution, that seemed to help a lot of people: “emerge –buildpkgonly –nodeps shadow && emerge -C pam-login && emerge –usepkgonly shadow”

After executing the above, my system was ready to go again. Hope this one helps a few people.

Note: The “buildpkgonly”, “nodeps” and “usepkgonly” options have to be used with two dashes. I’m mentioning this because it might not be displayed properly in your browser.

Yea, thanks alot. that really helped Though i’ve got some error message on first and last execute command, I’ve updated the shadow to latest version and could run emerge –update world without any problems, I guess ‘emerge -C pam-login’ helped

Thanks so much for posting this. The information was really helpful to me, and your solution worked beautifully, no errors whatsoever. Love your site by the way.

Stuart,
thanks a lot! I just started this site a month ago and I’m still trying to find my style and the right mix between tutorials, problem solving and news. Do you have any suggestions on how I could improve it? I’d love to hear from you.

Thanks! You’re the first hit when searching Google for “sys-apps/pam-login (is blocking sys-apps/shadow” and your solution works fine. (Mumbles something about why an OS would ship with such a problem…)

Thanks, this worked great. It’s been a while since I’ve used Gentoo, so I’m a bit rusty on portage. This post helped a lot.

Actually, I read on another website that new versions of shadow includes the same login program that pam-login provides. So the correct solution is to unmerge pam-login and update shadow– worked for me!

All I have to say is Thanks ! again you are the first one mentioned and for good reason, I am a noob working with Gentoo and this worked wonderfully. THanks for the great info !

buenos dias

had the same problem but your hint doesn’t solve it clean.
as aaron mentions the shadow packages now includes the
pam-login function so you don’t need it any more. so the
clean way is to remove the old pam-login from your system.

FYI the “-” character has several names, but none of them is “bracket” might want to use the term “dash” instead

J, thanks for the tip! It was kinda late when I wrote that post (uhmm, lame excuse).
