libnss3.so missing from /usr/lib

[André Ventura]

The libnss3.so is missing from /usr/lib and /usr/lib64 since the update of libnss3 from the version 3.12.9+ckbi-1.82-0ubuntu2 to 3.12.9+ckbi-1.82-0ubuntu3:

3.12.9+ckbi-1.82-0ubuntu2:

-rw-r--r-- 1 root root 1279784 2011-04-20 15:04 /usr/lib/libnss3.so
-rw-r--r-- 1 root root 1107684 2011-04-20 15:01 /usr/lib32/libnss3.so
-rw-r--r-- 1 root root 1279784 2011-04-20 15:04 /usr/lib64/libnss3.so

3.12.9+ckbi-1.82-0ubuntu3:

ls: cannot access /usr/lib/libnss3.so: No such file or directory
-rw-r--r-- 1 root root 1107684 2011-04-20 15:01 /usr/lib32/libnss3.so
ls: cannot access /usr/lib64/libnss3.so: No such file or directory

Thanks, but when running a development release (especially a pre-alpha release), it helps to check the changelog before reporting a bug (or subscribe to oneiric-changes)

  * Build for multiarch.

because of this jdownloader crashs. its possible to solv this to add a symlink from /usr/lib to the multi arch dir

[Chris Coulson (chrisccoulson)]

Well, that's a jdownloader bug

[André Ventura (afv)]

Thanks Chris but I read the log before (I'm subscribed to oneiric-changes).

Does then "build for multiarch" mean that instead of having one .so for each architecture we do have only one single file for all of them?
If so, I misunderstood, sorry. :) But shouldn't it be on /usr/lib/ instead of the particular /usr/lib64/ ?

Minecraft, for example, throws an exception when connecting to the minecraft.net server because it's looking at /usr/lib/:

java.security.ProviderException: Could not initialize NSS
...
Caused by: java.io.FileNotFoundException: /usr/lib/libnss3.so
 at sun.security.pkcs11.Secmod.initialize(Secmod.java:186)
 ...

*instead of the particular /usr/lib32/ ?

[Chris Coulson (chrisccoulson)]

No, there is a folder for each specific ABI now. If you run "dpkg -L libnss3", you will see where the libraries now live

[xyloman (xyloman)]

I was able to get around this issue by performing the following command: sudo ln -s /usr/lib/i386-linux-gnu/libnss3.so /usr/lib/

[Micah Gersten (micahg)]

@xyloman
That's a good way to break other software. The idea with multiarch is that multiple architecture's should be co-installable. Your software should be patched to look in the proper multiarch dir. If your piece of software is from the Ubuntu archive, please file a bug against it and tag it multiarch. If it is not, please file a bug with the provider of the software.

[André Ventura (afv)]

Thank you for the explanation.

[Hanmac (hanmac)]

@Micah Gesten: hm i does not see an co-installable for the nss packages now, or will this added later?

[Micah Gersten (micahg)]

Multiarch was added to nss for oneiric as quoted in the changelog
entry by Chris Coulson above. If you are running natty or earlier,
you should not be affected by this.

[Matthias Klose (doko)]

while there should not be a symlink in /usr/lib, the .pc should not advertise that it is found in /usr/lib (same for nss-config).

[Launchpad Janitor (janitor)]

This bug was fixed in the package nss - 3.12.9+ckbi-1.82-0ubuntu4
