Before this i tried to uninstall mysql and i followed this

apt-get --yes purge mysql-server mysql-client
apt-get --yes autoremove --purge
apt-get autoclean
deluser --remove-home mysql
delgroup mysql
rm -rf /etc/apparmor.d/abstractions/mysql /etc/apparmor.d/cache/usr.sbin.mysqld /etc/mysql /var/lib/mysql /var/log/mysql* /var/log/upstart/mysql.log* /var/run/mysqld

It appears you don't have internet access during this attempt. Try to ping google.com or go to the internet and if you can then try to run again. I have had issues with internet access after waking up my laptop from sleep, so I would at least try "systemctl restart networking".

It may also be worth checking to see if the /boot/ partition is full. Run "df -h" and see how much space is available there.

I know my answer might sound a bit silly, but you cannot forget to check the basics before trying to update/upgrade/install packages.
