removable_storage_test crashed with OSError in write_file(): [Errno 30] Read-only file system:

Only occuring when using an SD card set to the locked position.

Can you verify that your SD card is not locked (there should be a little slider to lock or unlock the card.

Once you've done that, can you send the output of the following after you insert the card?

/usr/share/checkbox/scripts/removable_storage_test -l --memorycard sdio usb scsi
/usr/share/checkbox/scripts/removable_storage_test -s 67120000 --memorycard sdio usb scsi

and also, just for kicks, try this:

touch /path/to/mediacard/foo.txt

obviously, use the actual path which should look something like this:

/media/USERNAME/MEDIACARDNAME/

OH... rubbish... I completely missed your second comment.

Yes this will happen when you use a locked media card. When the card is locked, the OS mounts it as read only, which makes running a test that actually writes data to the card rather impossible.

So, your bug is not really a bug. BUT you've pointed out a weakness in the test description. I'll amend the media card tests to be sure to specify an unlocked device explicitly.

You can ignore my requests in comment #3

Fix Commited means 'in trunk' (I know it has a lot of meanings, but now we have a release process it should mean this). This hasn't been merged yet so it's not Fix Commited.

This bug was fixed in the package checkbox - 0.16.1

---------------
checkbox (0.16.1) saucy; urgency=low

  * New upstream release (LP: #1180545):

  * Launchpad automated translation updates

  [ Alberto Milone ]
  * scripts/graphics_stress_test, scripts/rotation_test: make sure to
    always reset the "screen" variable. Somehow the NVIDIA driver manages
    to make it unusable after the first time. (LP: #1172667)

  [ Brendan Donegan ]
  * checkbox/parsers/submission.py - publish kernel-release information to
    interested parties.
  * scripts/rendercheck_test - change nargs='+' to action='append' for blacklist
    option so it works as expected.
    jobs/rendercheck.txt.in - blacklist gradients test as it is known to produce
    false positives. (LP: #1093718)
  * plugins/hexr_transport.py - added plugin for submitting to HEXR and
    certification based on certify_new_transport from checkbox-certification.
    examples/checkbox-qt.ini - blacklisted hexr_transport as we won't use it
    examples/checkbox-cli.ini - blacklisted hexr_transport as we won't use it
    examples/checkbox-urwid.ini - blacklisted hexr_transport as we won't use it

  [ Daniel Manrique ]
  * Ensured that button strings from the "continue" dialog are translatable
    (LP: #1176695)

  [ Jeff Lane ]
  * checkbox/parsers/cpuinfo.py - split on first instance of ':' in cpuinfo
    output lines to avoid splitting into more than 2 items. Also fixed a pep8
    issue discovered while working on this. (LP: #1180496)
  * scripts/cpu_offlining: Modified script to no longer offline cpu0 to resolve
    a bug on ARM. Modified output so most of it is redirected to stderr for
    fail cases, we don't need that much for success cases. (LP: #1078897)
  * jobs/mediacard.txt.in: Modified test instructions to be less confusing
    (LP: #970857)
  * scripts/cpu_topology: define the cpuinfo nested dicts on creation rather
    than define elements during parsing of /proc/cpuinfo (LP: #1111878)
  * scripts/lsmod_info: Corrected error handling for the check_output() call to
    trap the correct error. (LP: #1103647)
  * jobs/camera.txt.in: removed an extraneous requres line for gir1.2
    scripts/camera_test: added code to determine what version of gst we're
    using and set video type and plugin accordingly. (LP: #1100594)
  * scripts/network_check: added ability to specify custom target URL for
    debugging failures (LP: #1128017)
  * scripts/removable_storage_test: Added error handling to trap OSError on
    non-writable media and modified output to handle subsequent
    ZeroDivisionError issues when summarizing test results.
    jobs/media.txt.in: Modified instructions for SD/SDHC to specify using
    UNLOCKED cards to avoid issues when testing read-only media (LP: #1153894)

  [ Sylvain Pineau ]
  * jobs/suspend.txt.in, scripts/gpu_test: Remove the need of running the script
    with the root user, restore the workspaces switch and the HTML5 video
    playback ; remove the extra suspend/resume (LP: #1172851)
  * checkbox/parsers/udevadm.py: Only filter devices without product AND vendor
    information (LP: #1167733)
