Update to HA OS 18.0 - failure / timeout

Dear All,

I am using Home Assistant on VirtualBox.

I get this and I am trying up update:

From the logs it results that since the file is relatively large and the download rate is so slow, the update fails due to timeout. Confirmed from logs. Also did a test on CLI and watched it try to download in real time. Basically it would have taken over an hour at the rate it was going.

I may stand corrected - but is there any other way to install this update please?

Many thanks.
