initramfs-tools 0.142ubuntu12 fails on upgrade: wrong multiarch libdir Edit

[Thomas Schiex]

I just upgraded my system from Lunar to Mantic. initramfs is systematically producing messages such as:

  E: /usr/share/initramfs-tools/hooks/dhcpcd failed with return 1.

Looking into the corresponding bash script shows that the penultimate line produces an incorrect result:

  multiarch_dir=$(ldd /usr/sbin/dhcpcd | awk '/libc.so./ { print $3 }' | cut -f3 -d/)

stores "lib" instead of x86_64-linux-gnu in my case.

the correct line (tested) should be:

  multiarch_dir=$(ldd /usr/sbin/dhcpcd | awk '/libc.so./ { print $3 }' | cut -f4 -d/)

since ldd produces

 libc.so.6 => /usr/lib/x86_64-linux-gnu/libc.so.6 (0x00007f5baec00000)

Thank you for taking the time to report this bug and helping to make Ubuntu better. I'll change that code so support both /lib and /usr/lib:

multiarch_dir=$(ldd /usr/sbin/dhcpcd | sed -En 's;^.*/lib/([^/]+)/libc\.so\..*$;\1;p')

This bug was fixed in the package initramfs-tools - 0.142ubuntu13

---------------

  * Support usr-merged library path when detecting mutliarch dir (LP: #2037156)
