As i can guess you did bridge mode for Internet but , your dhcp not providing IP address to your port or you have not enabled networking. so , it showing like this

eth0      Link encap:Ethernet  HWaddr e8:11:32:db:1b:a5  
          inet6 addr: fe80::ea11:32ff:fedb:1ba5/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:68323 errors:0 dropped:0 overruns:0 frame:0
          TX packets:51953 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000 
          RX bytes:82498217 (82.4 MB)  TX bytes:4621046 (4.6 MB)

lo        Link encap:Local Loopback  
          inet addr:127.0.0.1  Mask:255.0.0.0
          inet6 addr: ::1/128 Scope:Host
          UP LOOPBACK RUNNING  MTU:65536  Metric:1
          RX packets:9075 errors:0 dropped:0 overruns:0 frame:0
          TX packets:9075 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:0 
          RX bytes:916870 (916.8 KB)  TX bytes:916870 (916.8 KB)

Solution: start your network-manager using

sudo service network-manager start

or use if already started

sudo service network-manager restart

or

sudo ip link set eth0 up 

or

sudo nmcli nm enable true

or enable using GUI

network-manager--> Enable Networking and connect wired connection

or

if you still face problem then it means your wifi dhcp not providing ip to VM then you can change mode bridge to NAT for internet then you will get private ip and will able to connect internet

Apart from the bridged mode, I had to disable ipv6 as per this post to get it working: https://superuser.com/questions/1146122/ubuntu-virtualbox-guest-does-not-get-ipv4-in-bridged-mode/1148247#1148247?newreg=7c77aaf0882540148a3700242cd05d0b

Pasting the steps from above: Open /etc/default/grub

In this file, find this line:

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash"

and change it to:

GRUB_CMDLINE_LINUX_DEFAULT="ipv6.disable=1 quiet splash"

Save the file and update GRUB by running:

sudo update-grub

Now reboot the VM. Next time it comes up with appropriate ipv4 address.
