Bug Description


here is a python exception I got while reporting a bug:

Traceback (most recent call last):
  File "/usr/lib/python3/dist-packages/apport/report.py", line 198, in _run_hook
    symb['add_info'](report, ui)
  File "/usr/share/apport/general-hooks/ubuntu.py", line 89, in add_info
    check_attachment_for_errors(report, attachment)

    report['DpkgTerminalLog'] = '\n'.join([str(line.decode('utf-8')) for line in lines])
  File "/usr/share/apport/general-hooks/ubuntu.py", line 508, in <listcomp>
    report['DpkgTerminalLog'] = '\n'.join([str(line.decode('utf-8')) for line in lines])
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe2 in position 3070: invalid continuation byte

This bug was fixed in the package apport - 2.20.10-0ubuntu1

apport (2.20.10-0ubuntu1) cosmic; urgency=medium

  * New upstream release:
    - backends/packaging-apt-dpkg.py: when using a permanent sandbox better
      check for the package being already available thereby reducing quantity
      of downloads.
    - apport/report.py: Use timeout parameter in subprocess to limit how long
      we'll wait for gdb to return information as gdb can hang with some core
    - data/apport: Fix PEP8 issues
    - apport/ui.py: Include ProblemType in reports which are updated as
      package hooks may expect the report to have a ProblemType. (LP: #1766794)
    - test/test_ui.py: modify run_crash_kernel test to account for the fact
      that linux-image-$kvers-$flavor is now built from the linux-signed
      source package on amd64 and ppc64el. (LP: #1766740)
  * data/general-hooks/ubuntu.py: Fix UnicodeDecodeError when processing
    DpkgTerminalLog. (LP: #1766337)
  * data/general-hooks/ubuntu.py: Don't display a messy error if python or
    python3 is not installed. (LP: #1769262)
  * debian/apport.links: source_linux-signed.py -> source_linux.py package
    hook (LP: #1766740)
  * data/package-hooks/source_linux.py: Redirect bugs filed about the
    linux-signed source package to linux. (LP: #1766740)
