[Quix0r]

Step 1: Please describe your environment

• ZeroNet version: 0.7.2 r4555
• Operating system: Devuan Chimaera 4.0
• Web browser: Firefox ESC
• Tor status: enabled/available
• Opened port: yes
• Special configuration: $ cat zeronet.conf [global] open_browser = False threads_crypt = 3 threads_fs_write = 2 threads_fs_read = 4 language = en fileserver_ip_type = ipv4

Step 2: Describe the problem: While running siteVerify on a large site, I get the said error message:

$ python3 ./core/zeronet.py siteVerify 1TaLkFrMwvbNsooF4ioKAY9EuxTBTjipT

UnboundLocalError: local variable 'err' referenced before assignment

PS: I had to install missing gevent through pip before. The version from my distribution is rather old (20.9.0-2 versus 22.10.2) or otherwise a simple $ python3 ./core/zeronet.py --version doesn't work.

Steps to reproduce:

1. Just execute the above command, or try an other site white ZeroNet is running.

Observed Results:

• I got the above error message.

Expected Results:

• The command runs through without any error messages.
