Public bug reported:
In bug #1718582, a user has a corrupted ESP. This leads to the shim-
signed apport hook crashing with the following error:
Traceback (most recent call last):
File "/usr/lib/python3/dist-packages/apport/report.py", line 197, in _run_hook
symb['add_info'](report, ui)
File "/usr/share/apport/package-hooks/source_shim-signed.py", line 42, in
add_info
if directory:
UnboundLocalError: local variable 'directory' referenced before assignment
The relevant code is:
try:
directory = os.stat(efiboot)
except OSError as e:
if e.errno == errno.ENOENT:
report['Missing'] = '/boot/efi/EFI/ubuntu directory is missing'
return
if e.errno == errno.EACCES:
directory= True
if directory:
If errno is anything other than ENOENT or EACCES, this crashes with the
above traceback.
It would probably be better to at least re-raise e if it doesn't match
one of our expected errnos.
