When I try to open an executable (in this case exploit exercises protostar stack0), then the following message appears in a pop-up box:
Failed to open and attach to process: execv() failed: No such file or directory.
and I am unable to open any files because of this.
osboxes@osboxes:~/tools/edb-debugger/build$ ./edb --run ~/proto/bin/stack0 Icon theme "elementary" not found. Starting edb version: 1.1.0 Please Report Bugs & Requests At: https://github.com/eteran/edb-debugger/issues Running Terminal: "/usr/bin/xterm" Terminal Args: ("-title", "edb output", "-hold", "-e", "sh", "-c", "tty > /tmp/edb_temp_file_787768528_7578;trap \"\" INT QUIT TSTP;exec<&-; exec>&-;while :; do sleep 3600; done") Terminal process has TTY: "/dev/pts/5" comparing versions:  
At first I installed edb using apt-get. This problem occurred. Then I uninstalled and installed it manually from the source code (and fixed the segmentation fault issue by changing the plugins directory). The problem remains. It doesn't matter if I use --run or try to open it from the GUI.
I'm using Lubuntu. Linux 5.3.0-18. It's a VM downloaded from OSBoxes.
