I have a small sh script that I use to backup to a remote server. It worked on Ubuntu 16.04 for years, but now on 18.04 it fails. At first I thought it was a problem with anacron, but now I think it is a problem with the script itself or with dash. Here is what is happening:

I'd switch from using #!/bin/sh as your shebang to #!/bin/bash since you're expecting Bash features vs. /bin/sh or /bin/dash.
Also I can't tell for sure but it looks like you have a typo on the first line where there's a stray * over to the right.
#!/bin/sh *
^^^ Scroll over to the right to see it.
Example
$ cat script.bash
#!/bin/sh *
echo hi
Run directly:
$ ./script.bash
/bin/sh: *: No such file or directory
Run via sh:
$ sh script.bash
hi

Exactly, this asterisk is producing a syntax error when the shebang line is used, thus preventing the script from being run. OP’s script is not using anybashfeatures though, there’s no need to make it#!/bin/bash. A shebang line#!/bin/bash *throws an error as well.

@slm That doesn't make sense... You state in your answer "... since you're expecting Bash features ...", but the OP is clearly not using any bash features in his script. I agree with dessert that the#!/bin/bashadvice is misplaced. It's the "also" part of your answer that is the actual answer ;)

@marcelm - as I stated to dessert above, if someone is attempting to use the features of something, better to use it directly vs. indirectly. I'm not saying that the OP was actually using any Bash features per say, just that they're writing a Bash script so call it out directly vs.sh.
