perf broken on 4.11.0-9-generic (artful): /usr/lib/linux-tools/4.11.0-9-generic/perf: error while loading shared libraries: libbfd-2.28-system.so: cannot open shared object file: No such file or directory

[Trent Lloyd]

I am unable to launch perf on 4.11.0-9-generic (artful) running on artful-proposed

/usr/lib/linux-tools/4.11.0-9-generic/perf: error while loading shared libraries: libbfd-2.28-system.so: cannot open shared object file: No such file or directory

It seems this library is provided by binutils, however the symlink doesn't exist like it does on my xenial system for comparison.

lathiat@ubuntu:~$ dpkg -L binutils|grep bfd|grep so
/usr/lib/x86_64-linux-gnu/libbfd-2.28.51-system.20170627.so

lathiat@ubuntu:~$ ls /usr/lib/x86_64-linux-gnu/*libbfd*
/usr/lib/x86_64-linux-gnu/libbfd-2.28.51-powerpc.20170627.so /usr/lib/x86_64-linux-gnu/libbfd-2.28.51-system.20170627.so

On xenial:
root@hyper:~# ls /usr/lib/x86_64-linux-gnu/*libbfd*
/usr/lib/x86_64-linux-gnu/libbfd-2.26.1-system.so /usr/lib/x86_64-linux-gnu/libbfd.a
/usr/lib/x86_64-linux-gnu/libbfd-2.26-system.so /usr/lib/x86_64-linux-gnu/libbfd.so

Not clear to me where the bug lies here, so starting with the 'perf' binary by way of the kernel package. But may be an issue with something else. I did notice quickly running 'ldd' in /usr/bin that it seems other files are linking against the above so directly.

This bug is missing log files that will aid in diagnosing the problem. While running an Ubuntu kernel (not a mainline or third-party kernel) please enter the following command in a terminal window:

apport-collect 1702056

and then change the status of the bug to 'Confirmed'.

If, due to the nature of the issue you have encountered, you are unable to run this command, please add a comment stating that fact and change the bug status to 'Confirmed'.

This change has been made by an automated script, maintained by the Ubuntu Kernel Team.

I've got the same issue too with artful

[Colin Ian King (colin-king)]

There seems to be a missing symlink in /usr/lib/x86_64-linux-gnu

cd /usr/lib/x86_64-linux-gnu
sudo ln -s libbfd-2.28.51-system.20170627.so libbfd-2.28-system.so

and that allows perf to run

Doing a quick google, it seems third party binaries can get linked against this shared library as well possibly. Ran apport-collect for the extra logs; and both today's binutils and kernel upgrade haven't fixed it.

Thinking we might need to propose for affecting binutils?

[Trent Lloyd (lathiat)]

I rebuilt both binutils and linux-4.11.0-11 locally to see if anything changed.

binutils still has the same libbfd-2.28.90-system.20170718.so soname in the package

however perf in linux-tools is now linked against the new soname. So a rebuild may solve it however I am not entirely sure if this soname change made sense or not. I'm not familiar enough with how it works.. Building the current Debian version (2.28-6) renders libbfd-2.28-system.so

lathiat@ubuntu:/src/z$ ldd ./usr/lib/linux-tools-4.11.0-11/perf|grep bfd
 libbfd-2.28.90-system.20170718.so => /usr/lib/x86_64-linux-gnu/libbfd-2.28.90-system.20170718.so (0x00007fd09cbbf000)

lathiat@ubuntu:~$ ldd /usr/lib/linux-tools-4.11.0-11/perf |grep bfd
 libbfd-2.28-system.so => not found

[Trent Lloyd (lathiat)]

New binutils upload today of 2.29, which conflicts with linux-tools as it turns out it Depends binutils (>= 2.28), binutils (<< 2.29)

[Trent Lloyd (lathiat)]

Same problem with the new 4.11.0-12 upload, i'm assuming since binutils is still in -proposed it wasn't built against?

 linux-tools-4.11.0-12 : Depends: binutils (< 2.29) but 2.29-2ubuntu1 is to be installed

[Matthias Klose (doko)]

please use -proposed on your own risk. it's the area where packages stabilize. The kernel should always build with the proposed pocket enabled.

[Trent Lloyd (lathiat)]

This is resolved now.

I have "reopened" this bug as: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1718897 , as it still fails for me (a month later).
