[Bug 634487] Re: t1.micro instance hangs when installing java

 

On how to fix corrupted apt-get/dpkg:

1. Run: dpkg -l |grep -v -E "^ii"

This will list all packages that are either not in perfectly installed
state; either incompletely installed, or that have config files
remaining behind them after they have been uninstalled (or some other
variant). You can tell them apart by value in first column. (rc =
removed & conf-files; iU = install & unpacked). See listing header
("dpkg -l | head" for detailed meanings).

2. Run: dpkg -P package_name [package_name2] [package_name3 ...]

This will purge those incomplete packages.

Personally, I have removed all listed packages (as they were all related
to broken jre install), and dpkg was running without a problem
afterwards.

Bug description:
  Binary package hint: cloud-init

  I booted the 32bit EBS lucid AMI (ami-1234de7b) for a t1.micro
  instance. I attempted to install Sun Java. The instance hung during
  the install. Repros every time. Only repros on t1.micro instances. I
  tried adding swap in case it was an out-of-memory condition, and it
  still repro'd. No reboots or anything else like that were involved so
  it's not the same issue as #634102

  Console log snippet (full one attached):
