My packer freebsd builder failed because of this issue. I have tested this for a while with the same template. In most cases, the builder fails (truncated base.txz or truncated pkgng packages). Occasionally, the download and installation are successful. I booted one of these successfully created images with qemu and ran additio= nal tests. Test #1: fetch http://www.google.de The last byte is missing. Test #2: ping google.de PING google.de (172.217.23.163): 56 data bytes 64 bytes from 172.217.23.163: icmp_seq=3D0 ttl=3D255 time=3D622018725671.83= 2 ms wrong data byte #8 should be 0x8 but was 0xc0 [...] Test #3: pkg install curl wget One successful attempt after many truncated downloads.
