mc flag

Installing Ubuntu LTS offline via usb, and get stopped at Processing triggers for dbus (1.12.16-2ubuntu2.1) for a long period of time.

If I run the installer online, I seem to get stuck at the message subiquity/late/run.

which one do you recommend to install: ubuntu 20.04.3 or ubuntu 21.10
ua flag

I know in general the answer is 20.04.3 certainly.

but i have purchased a new laptop equipped with 11th gen Intel core i3 CPU and uefi boot. so new hardware support is important for me. also i will upgrade to Ubuntu 22.04 as soon as its release so it is important for me to install an Ubuntu version which will make upgrading simpler in coming months.
