@sagher
i would like the output of 'uname -a'

also comment out all the source links. you dont need them. then purge cache and run again. 'apt-get clean'

also check
/etc/resolv.conf

it should have good name servers. like

nameserver 8.8.8.8
nameserver 1.1.1.1

ensure that. then check
'ping google.com'


also make sure port 21, 53, and 80 are open in firewall.
may be do a 'ufw disable' and then try.

replying from mobile. so didnt notice the hits. you dont need to do what i said above. Just keep the links that is successfully connecting and comment out others. I mean all those with error (E) and ignored (Ign). Also commeng out thd source links. src

next clean it.

apt-get clean

now run update.
