I'm on Ubuntu 13.04 and I am experiencing a lot of issues like:

  • Crash when waking up from suspend
  • Crash when logging out of session
  • Random crashes in Unity (not in i3wm)
  • Slow boot
  • Some errors during boot

I've been working on this for a while, and someone suggested that it must be some sort of low level error and told me to try and update the kernel before I file a bug report.

But when I try to update to the mainline kernel from kernel.ubuntu.com I get this error when installing the headers-generic-amd64 file:

martinux@g580:~/Downloads$ sudo dpkg -i linux-headers-3.9.4-030904-generic_3.9.4-030904.201305241545_amd64.deb

I'm on a Lenovo g580 and would like to know if there is a possible fix for this or if I should just file a bug report and install 12.10 in stead.

There is an open bug in the bcmwl package:

https://bugs.launchpad.net/ubuntu/+source/bcmwl/+bug/1157880

So if you have a Broadcom wifi card, you need to downgrade to 3.8.0 to get the wireless driver building.

As it turns out, the new kernel was in fact installed even though I got an error.

I was also advised (I did not try it) to try

 sudo apt-get purge bcmwl-kernel-source

to avoid the error.
