Comment 0 for bug 1867473

ENVIRONMENT:

Ubuntu 20.04, fully upgraded as of Mar 14 2020.

ISSUE:

Running apport-retrace -v -s -R -S system ./crash/_usr_bin_texstudio.1000.crash gives me the following stacktrace:

--- stack trace ---
#0 0x00007fa95a8273eb in ?? ()
No symbol table info available.
#1 0x0000000000000000 in ?? ()
No symbol table info available.
--- source code stack trace ---
#0 0x00007fa95a8273eb in ?? ()
#1 0x0000000000000000 in ?? ()

EXPECTED BEHAVIOR:

apport-retrace should actually give a meaningful symbolic backtrace, after all it downloads tons of debug packages to a sandbox directory, but it seems gdb is unable to use them currently.

NOTES:

When just running apport-retrace without sandbox the backtrace is a lot more meaningful:
