GNU/Linux distributions usually provide package managers which handle installation, configuration and removal of software packages. Wireshark is provided by several distributions and some of them help in configuring dumpcap to allow capturing even for non-root users.
Debian, Ubuntu and other Debian derivatives
By installing Wireshark packages non-root users won't gain rights automatically to capture packets. To allow non-root users to capture packets follow the procedure described in /usr/share/doc/wireshark-common/README.Debian
Other Linux based systems or other installation methods
Running Wireshark (or any other network capture/analyzer, for that matter) on Linux needs root privileges. Therefore, you have to have root privileges when starting Wireshark, else you can't capture data. Please note that you don't have to login as root when starting your computer, you can use su(1) or sudo(8) for that purpose. However, this remains unsecure as the dissectors, the parts of Wireshark which parse the captured data, run with root privileges as they did before. A much safer solution would be to su(1) to root, then use the bundled dumpcap to dump the data (for example, you can evoke dumpcap by using "dumpcap -w ./dumpfile", which will dump the packets to the file "dumpfile" in the current working directory. See "dumpcap -h" for details). You could also use tcpdump for this purpose. The advantage of this solution is, while dumpcap/tcpdump still run as root, you can run Wireshark as a ordinary user and load the data you captured previously, so effectively this is kinda "privilege separation by hand".
Setting network privileges for dumpcap
1. Ensure your linux kernel and filesystem supports File Capabilities and also you have installed necessary tools.
2. "setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap"
3. Start Wireshark as non-root and ensure you see the list of interfaces and can do live capture.
Limiting capture permission to only one group
1. Create user "wireshark" in group "wireshark".
2. "chgrp wireshark /usr/bin/dumpcap"
3. chmod 754 /usr/bin/dumpcap
4. "setcap 'CAP_NET_RAW+eip CAP_NET_ADMIN+eip' /usr/bin/dumpcap"
5. Ensure Wireshak works only from root and from a user in the "wireshark" group
