@GillesNeedsHelp Could you confirm the following:
- that your local network IP address is 192.168.7.xxx ?
- in you post above you noted that you originally had network access on this Linux VM, and for a "little while" after upgrading it, have I read this correctly ?
- What is the network status of your other VMs ?
Could you perform the following:
with the Linux VM powered down, within the Virtual Machine Settings for the VM set the Network Adapter to NAT, power up the VM and login to Linux
then open a command prompt and type ifconfig -a and then ip link show review and note the results.
Request: please just do one thing at a time, in a methodical manner, otherwise it's virtually impossible to determine the progress of each stage of the investigation.
