Hi

I got a new laptop and I took the chance to upgrade my OS. Now I have Ubuntu 20.04. Today I had an unexpected behavior. After compilation, I issued the setcap command, but then I got:

$ sudo setcap cap_net_raw,cap_net_admin=eip run/dumpcap
$ ./run/dumpcap -D
./run/dumpcap: error while loading shared libraries: libwsutil.so.0: cannot open shared object file: No such file or directory

Removing the capabilities gave my dumpcap back.

$ sudo setcap -r run/dumpcap
$ ./run/dumpcap -D
1. wlp59s0
2. nlmon0
3. lo (Loopback)
[...]

Another user from ask, hit the same problem, like 1 year ago, on ubuntu 18: https://ask.wireshark.org/question/12115/wireshark-dumpcap-with-setcap-set-to-no-root-capture-failes-to-start-in-ubuntu-1810/

I'm still trying to figure out if I made other configurations before, but I can't recall anything useful.

Any ideas?

Thanks.

Dario.
