I have a HP 15 ac650tu laptop. The laptop has Windows 10 installed and is working fine.
I am trying to install Ubuntu 18.04, using a bootable USB drive. Initially I faced an ACPI error. After checking on web, I resolved it by setting acpi=off.
Now after running with acpi=off option, the Ubuntu hangs at the error below.
Writing new source list
Source list entries for this disc are:
deb cdrom:[Ubuntu 18.04.2 LTS _Bionic Beaver_ - Release amd64 (20190210)]/ bionic main restricted
Repeat this process for the rest of the CDs in your set
