I installed RocketChat.
I installed RocketChat CTL.
And then I tried to run /usr/local/bin/rocketchatctl update
Which results in:
Updates could be risky, you can use the backup option # rocketchatctl backup, to create a backup of the rocketchat database first. Please check that you have enough space in your system to store the backup.
/usr/local/bin/rocketchatctl: line 909: [: 3.15.0: unary operator expected
Could not determine if updates available for RocketChat server.
When I manually set the version to 3.14.1 it works with the update.
It seems that the version get command is broken.
