I'm experiencing this problem as well. I suggest all of those with the problem post some information to help narrow the issue down. In my case I'm using a newly installed SSD and have a feeling the slow linux- headers unpacking is just a side effect of slow write speeds.
Hard drive: SSD (Corsair CSSD-V60GB2 w/ firmware update) Size: 60GB Filesystem: ext4 with dm_crypt full-disk encryption Ubuntu 12.04 LTS Kernel: 3.2.0-36-generic Approximate time to unpack: 30 min # hdparm -tT /dev/sda2 /dev/sda2: Timing cached reads: 6526 MB in 2.00 seconds = 3270.42 MB/sec Timing buffered disk reads: 398 MB in 3.00 seconds = 132.57 MB/sec # dd if=/dev/zero of=tempfile bs=1M count=1024 1024+0 records in 1024+0 records out 1073741824 bytes (1.1 GB) copied, 16.0206 s, 67.0 MB/s During the delay: iHR linux-headers-3.2.0-37-generic 3.2.0-37.58 Immediately after the delay: iU linux-headers-3.2.0-37-generic 3.2.0-37.58 linux-headers is unpacking 8152 small files, so my hunch is that there is nothing special about the package, nor a problem with dpkg, but instead that linux-headers is simply demonstrating the already slow disk speeds we have but don't notice with other packages. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/947664 Title: Unpacking linux-headers unbelievably slow in Lubuntu Precise (Beta 1) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dpkg/+bug/947664/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
