adding system image vyos-1.2.0-rolling+201906181619-amd64.iso on existing VyOS instance (vyos-1.2.0-rolling+201906121251) on hyper-v, I get after MD5 checksum check the following syntax error:
/opt/vyatta/sbin/install-get-partition: line 314: syntax error near unexpected token `fi'
/opt/vyatta/sbin/install-get-partition: line 314: ` fi'
But not in other instance on AWS EC2.
