Just some things as suggestions to your problem:

The "No MTA installed" line indicates that cron wants to send a mail to  
you with the output of your script. This mail could tell you the problem,  
as it would contain the error messages.

I've installed "nullmailer" on my BBS. This is a bare-bones MTA which  
sends out all mails generated on the system to a specific e-mail-address.
It is a Debian package. In /etc/nullmailer/adminaddr, I wrote my e-mail  
address, and in /etc/nullmailer/remotes, I wrote my mailserver.
If this system is not used for any other SMTP mail stuff, this should work  
just fine.

As for the cron PATH problem:
In my /etc/crontab (on a Devuan/Debian system), there are two lines at the  
beginning:

SHELL=/bin/sh
PATH=/usr/local/sbin:/usr/local/bin:/sbin:/bin:/usr/sbin:/usr/bin

So I guess, that all the scripts called from /etc/crontab will get these  
environment variables and thus will get the PATH from here.
You could try, if this works with your cron.

If not, I would suggest to add the PATH line from above to the start of  
your scripts or to explicitly write the full path of the programs in the  
scripts.

Sourcing /etc/profile should also work but it would include other stuff  
that might not be needed. And sourcing a bash_profile from the home  
directory of some user would work but I would not recommend it as it would  
mish-mash stuff from users and the system, which is not a clean solution.

I hope that helps you a little.

Regards,
Anna
