dumpcap: SIOCSIWMODE failed: Operation not permitted

When I try to capture in monitor mode in Wireshark after capturing a few packets I get the following error:
Unknown message from dumpcap, try to show it as a string: Can't restore interface wlp18s0 wireless mode (SIOCSIWMODE failed: Operation not permitted).
Please adjust manually.
> ls /usr/sbin/dumpcap -l
-rwxr-x---. 1 root wireshark 83632 Nov 7 18:34 /usr/sbin/dumpcap
> getcap /usr/sbin/dumpcap
/usr/sbin/dumpcap = cap_net_admin,cap_net_raw+eip
Even when I run wireshark with root user I get that error.
Any suggestion?

This is a libpcap issue. You would probably also see it if you try capturing in monitor mode with tcpdump on that interface by using the -I flag and a -i flag specifying that interface. Please report it on the libpcap issue tracker on GitHub.

I had the same problem. Run the airmon-ng binary:
sudo airmon-ng start wlan0.
A virtual interface on top of wlan0 will be created with monitor mode enabled.
The output I got using ifconfig is shown below
mon0 Link encap:UNSPEC HWaddr 88-9F-FA-79-66-C1-3A-30-00-00-00-00-00-00-00-00
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:2695503 errors:0 dropped:1416652 overruns:0 frame:0
TX packets:0 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:596242234 (596.2 MB) TX bytes:0 (0.0 B)
Then open wireshark, and select this interface for capturing packets in monitor mode.
