sh: 9: [[: not found
sh: 55: [[: not found
2015-02-11 17:35:47 URL:https://raw.githubusercontent.com/eli-schwartz/calibre-installer/master/linux/calibre-upgrade.sh [2612/2612] -> "/usr/bin/calibre-upgrade.sh" [1]

Code:
0 6 * * 5 /usr/bin/calibre-upgrade.sh > /dev/null 2>&1

Calibre is up-to-date
message.
