I forgot to mention this issue when i first use raspup. I unable to launch vivaldi.sfs made using the sfs downloader. I tried to launch vivaldi-stable as root, but what i got was 'segmentation fault' error. I recalled tried to download vivaldi.sfs as 'spot' too, but still failed to launch vivaldi.
Chromium on the other hand, can be launched successfully, but is too slow and not usable. My experience told me that on raspbian, chromium is too slow and unusable too. But on rapberry pi zero, only dietpi able to run chromium, of course, do not expect to watch youtube videos in browser mode, for lite browsing it is not fast, but still usable and able to load pages with heavy java script with satisfactory time.
Below is the spec:
Board: Raspberry pi zero
OS: Raspup 8.2.1
Package: latest Vivaldi v4.0.sfs made with builtin tools (Menu > Setup > Download System SFS Files > Select Vivaldi > Select root)
Error code: Segmentation fault
