When we install Wireshark in the deepin application store, it is generally impossible to capture packets normally; therefore, we need to change the usage permissions ourselves. The steps are as follows:
(1) Add a wireshark user group
sudo groupadd wireshark
(2)将dumpcap更改为wireshark用户组
sudo chgrp wireshark /usr/bin/dumpcap
(3)让wireshark用户组有root权限使用dumpcap。
sudo chmod 4755 /usr/bin/dumpcap
(4)将需要使用的用户名加入wireshark用户组，我的用户名是matrix,用户名就是安装系统的时候，设置的用户名；
sudo gpasswd -a matrix wireshark
以上就是所有的步骤，大家可以尝试一下，我试过了，确实可以解决。
