[SOLVED] Apt update - stuck on 0%

Issue

I have problem with "0% Working". I saw same posts before, tried to do what there adviced but it dont help me. My system is:

  lsb_release -a No LSB modules are available. Distributor ID: Ubuntu
 Description:    Ubuntu 16.04.4 LTS Release:        16.04 Codename:    
 xenial

I have

I have Google DNS

# Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
#     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
nameserver 8.8.4.4
nameserver 8.8.8.8

I have good ping to ubuntu site:

PING us.archive.ubuntu.com (91.189.91.26) 56(84) bytes of data.
64 bytes from hanger.canonical.com (91.189.91.26): icmp_seq=1 ttl=54 time=127 ms
...

Here my /etc/apt/sources.list https://pastebin.com/usJHp95b

Now i see that i cant install any programm like "dig" or nmap:

sudo apt install nmap
Reading package lists... Done
Building dependency tree
Reading state information... Done
E: Unable to locate package nmap

Previos time all worked fine. What i did before: 1) Installed OpenVPN for tests. 2) Get new router from my ISP but seems like i did there same settings for network. 3) Our dear goverment block Telegram (over 15 million IP adress Google and Amazon, maybe here a problem?)

Also i have message from system when i logged in system from monitor (not ssh), "sendbytes: NAK bailout. " its repeat every 5 sec +-

Sorry for bad english! Any suggestions?

Solution

Two suggestions:

• Try changing the update server location from US to where your proxy is hosted(Russia maybe?) in "Software and Updates":

• Try changing the sources.list to suit your demographics here.
