Adding variable TERM to environ is enough to solve the problem.
apport.memdbg("before calling gdb")
+ environ['TERM'] = os.environ.get('TERM', '')
subprocess.call(gdb_cmd, env=environ)
Now 'lay asm ' and lay 'regs' provide valuable information.

Title:
Cannot enable the TUI: error opening terminal [TERM=<unset>]
Status in apport package in Ubuntu:
New
Bug description:
I try to analyze a crash report on riscv64. I am connected to the
system via ssh.
sudo DEBUGINFOD_VERBOSE=1 apport-retrace --gdb --sandbox system
--cache ~/.cache/apport-retrace
/var/crash/_usr_bin_qemu-x86_64-static.0.crash
In the opened gdb I try to show the source:
(gdb) lay src
Cannot enable the TUI: error opening terminal [TERM=<unset>]
My expectation is that gdb shows the source layout.
gdb works fine outside apport-retrace.
# echo $TERM
xterm-256color
