I have a Raspberry Pi 2 with Ubuntu 14.04 installed and I'm experiencing a strange problem. I'm attempting to use sbuild to build a Debian package and everything works well enough for the first few seconds...
ubuntu@ubuntu:/tmp/pkg/pkg-0.0.1$ sbuild
dh clean
dh_testdir
dh_auto_clean
...
However, sbuild runs into some issues while attempting to install some of the packages:
...
Preparing to unpack .../libc6_2.19-0ubuntu6.6_armhf.deb ...
Unpacking libc6:armhf (2.19-0ubuntu6.6) over (2.19-0ubuntu6) ...
It stops at this point and the disk I/O LED becomes saturated.
I had two other terminal windows open with top and iotop running. According to top, the CPU and memory usage is as follows:
%Cpu(s): 4.7 us, 1.9 sy, 0.0 ni, 70.2 id, 23.2 wa, 0.0 hi, 0.0 si, 0.0 st
KiB Mem: 946112 total, 657852 used, 288260 free, 41276 buffers
According to iotop:
Total DISK READ : 0.00 B/s | Total DISK WRITE : 0.00 B/s
Actual DISK READ: 0.00 B/s | Actual DISK WRITE: 0.00 B/s
Nothing seems to be reaching its limit. None of the mounted partitions are more than 31% full.
What could possibly cause this anomaly and what can I do to fix this issue?
