I use whonix a few year, and i really appreciate developers work, but after update to whonix 15 my workstation die. Every new workstation 15-version did the same after second or third launch. I dont think its fault of whonix, more likely its some rare bug of virtualbox.
Therefore i try to make new custom workstation based of debian. I used this instruction https://www_whonix_org/wiki/Other_Operating_Systems with 100% - precision
but i cant communicate my WS with standart gateway. In addition i cant whonificate another WM that was installed from netinst-iso.
So, this instruction is actual or maybe something changed? I really broke my mind trying to solve this problem.
