apportcheckresume crashed with AssertionError in _assert_bin_mode(): file stream must be in binary mode

Status changed to 'Confirmed' because the bug affects multiple users.

Hit this as well following a suspend/resume that ended in a poweroff (dunno why). This looks like it may be a regression due to the switch to python3. I'm not sure how to debug this, because there doesn't seem to be a backtrace here to tell us which stream is in the wrong encoding, and running /usr/share/apport/apportcheckresume by hand results in a different crash (bug #1046092).

Andy, can you provide any guidance on debugging this?

The backtrace shows it failing when writing the report file on line 84. This is because write in problem_report.py checks that it was opened in binary mode, with a comment that it is required. Changing line 82 in apportcheckresume so it opens report_file in binary mode with 'wb' instead of just 'w' seems to fix it.

Running it manually triggers bug #1046092 because the script assumes /var/lib/pm-utils/status exists. Not sure if that was the case all along, or if either the change to python3 or changes to attach_file_if_exists changed the behavior.

I was not resuming from suspend when this happened, it was a minute or two after a fresh boot on my Asus EEE 1000. Probably something with power management as Andy said.

Ajit: why did you mark the bug as 'fix released'? Which change of code fixed the issue?

Fixed in trunk r2485.

This bug was fixed in the package apport - 2.5.2-0ubuntu2

---------------
apport (2.5.2-0ubuntu2) quantal; urgency=low

  * data/general-hooks/ubuntu.py: Add "package-from-proposed" tag if the
    installed package version is available from -proposed, but not from
    -security and -updates. (LP: #1050853)
  * Merge fixes from trunk:
    - data/apportcheckresume: Open report file in binary mode. (LP: #1040353)
    - packaging-apt-dpkg.py: When throwing ValueErrors, show the non-existing
      package name. This makes it easier to debug such crashes.
    - launchpad.py: Replace characters from tags which are not allowed by
      Launchpad with '.' (LP: #1029479)

Each time I start my computer the system hangs one to five or six times, after Grub, when it starts to load the system. When at last the system loads there are no prblems . I tried to stop the computer with `suspend'. After restarting I got a problem that looked like this problem. Maurits Wijzenbeek

Has this been fixed because I'm still having this problem....

I got it too.

I have a system76 panp9

have same problem

Please be more specific if you still have this problem -- are you perhaps running Ubuntu 12.04 LTS ("precise")?

I for one also get a prompr to send an error report about apportcheckresume on every boot after the batteries ran out or if the laptop is intentionally or accidentally suspended/resumed.

Here's the output of manually running on a terminal:

That's bug 1046092.

I have same problem in quantal 12.10.

Same basic symptoms as above- usually happens on trying to resume from sleeping- Almost always requiring a hard-reboot - then then sometimes on the following boot.

This was a clean install of ubuntu-12.10-desktop-amd64.iso that was upgraded by:
sudo apt-get install ubuntu-gnome-desktop ubuntu-gnome-default-settings

I am also still having this now on raring ringtail 13.04, was on 12.10 too.

I still have this problem with ubuntu 12.10. When was this fixed?

It can't be the same problem, this bug was fixed in 12.10. If you still experience a similar crash, can you please file a new report? Thanks!
