I see people having trouble to install red alert in Ubuntu. Most probably Ubuntu 64 bit.
I'm using Debian Jessie 64bit and I get the same error message:
[...]
/var/lib/dpkg/info/tiberiansunonline.postinst: 2: /var/lib/dpkg/info/tiberiansunonline.postinst: [[: not found
[..]
This issue can be solved by replacing the wine64 package by wine32.
Following commands should lead you to the successfull install:
sudo dpkg --add-architecture i386
sudo apt-get install win32
sudo dpkg --purge wine64
sudo dpkg -i redalertfull_1.0_all.deb OR sudo dpkg -i redalertonline_1.0_all.deb
Good luck!
