I'm using a fresh and updated Deveuan xfce system.  Snapshot copies file system through to /var and then crashes, /var/log info below:-

cpio: kernel/x86/microcode/GenuineIntel.bin not created: newer or same age version exists
15540 blocks
+ zcat
+ cpio -i

gzip: stdin: not in gzip format
cpio: premature end of archive
+ exit_code=2
+ '[' 2 -ne 0 ']'
+ cpio -i
cpio: kernel/x86/microcode/GenuineIntel.bin not created: newer or same age version exists
15540 blocks
+ xzcat
+ cpio -i
xzcat: (stdin): File format not recognized
cpio: premature end of archive
+ exit_code=2
+ '[' 2 -ne 0 ']'
+ echo 'Decompression error'
+ exit 1

Any suggestions would be appreciated.  Thanks in advance.
