No interface can be used for capturing in this system with the current configuration.
(couldn't run /usr/bin/dumpcap in child process: permission denied)
Tell me how to avoid it.

you could run it temporary as root - this would be a workaround regarding the missing interfaces. Wireshark should display a dialog/warning regarding root usage in that case – dufte Mar 22 '16 at 12:16

As @Tim already mentioned - this problem was discussed before already. This post gives the proper solution - just tested it in 14.04 and it is still valid & working
The following is a 100% quote from here.
Open a terminal by pressing Ctrl+Alt+T and type the following commands:
sudo dpkg-reconfigure wireshark-common
press the right arrow and enter for yes
sudo chmod +x /usr/bin/dumpcap
you should now be able to run it without root and you will be able to capture.

```sudo chmod +x /usr/bin/dumpcap``` was the only missing step. I granted root privileges to all users during wireshark installation so no need to run dpkg-reconfigure. – Sandoval0992 Jul 02 '22 at 13:56
