Hello friend, its maulana

today we will try to install vnc viewer in ubuntu 20.04

lets begin

1. open mozila/chrome
2. go to https://www.realvnc.com/en/connect/download/viewer/
3. download vnc for linux
4. we got a problem due to incorrect permission so we try using terminal
5. we got another error dpkg: error: dpkg frontend lock is locked by another process
you can solve this problem using
First run:
lsof /var/lib/dpkg/lock
Then make sure that process isn't running:
ps cax | grep PID
If it is running:
kill PID
#wait
kill -9 PID
Make sure process is done:
ps cax | grep PID
Then remove the lock file:
sudo rm /var/lib/dpkg/lock
Let dpkg fix itself:
sudo dpkg --configure -a
You should be fine afterwards :)
6. now we hava been install vnc viewer, lets try
7. insert the ip addres from your raspberry/computer that you want to remote
8. Finnaly, we can remote the raspberry

Thanks for watching, hope can help you guys
