Hello, I want to buy arduino micro,since it does not have Wi-Fi built in.so can I connect it to a WiFi device and start using it like MKR1010 which has an inbuilt Wi-Fi.please reply asap,thankyou.
Yes, you can connect a WiFi module to the Micro if you like. The most popular is the ESP8266. But you can also just use the ESP8266 by itself as a WiFi Arduino Board.
I ENCOUNTERED another problem with my arduino due i.e., I am using linux and when I upload my program it says

//These many errors what does it mean?
This is the part you need to focus on:

Caused by: jssc.SerialPortException: Port name - /dev/ttyACM0; Method name - openPort(); Exception type - Permission denied.
I believe this means you need to add your user to the dialout group so it has permission to access the port.
