# Fix talkkonnect Terminal Initialization Error
################################################################################
# This script fixes the "Cannot Initialize Terminal" error that occurs when
# talkkonnect is run as a systemd service without a TTY.
#
# The fix adds:
#   - Environment="TERM=dumb" to use minimal terminal mode
#   - StandardInput=null to prevent terminal initialization
