Hi.. What I'm about to write is more about WHY this is happening. I've
not used Caja, but I *might* have at least some insight.. kinda sorta.
Does Caja open up in part by using a web browser to do whatever it
does?

I've just tried "apt-cache show caja" and got some insight again. It's
talking about file managers in the description. I remember WAYYY back
when I was using Knoppix that something would open file manager type
sessions.... in a web browser. "apt-cache search kde web browser" to
the rescue when it reminded me that the web browser was Konqueror.

*IF* Caja somehow interacts with a web browser, that's what is going
on, that's why you're seeing that message. I learned about that
message accidentally when I was logged in as root while having
problems debootstrap'ing one time.

Root is and always has been about get in, get the barest minimum admin
duties accomplished as needed, and get out. So our systems default to
where we are *not allowed* to use games...... and we are *not allowed*
to use browsers for casual browser without giving it an extra special
flag. That extra special flag means we're capable and that we're
consciously aware we are web browsing as root.

A quick search on the Net hints that's what that "--no-sandbox" flag
is about. That's not what I used to get my browser to work. I was
offered the "--user-data-dir=DIR" flag during my fails.

After struggling for a long time, I realized what a similar error
message was trying to tell me in my case... use the offered flag along
with the "chromium" command. When you do, you're acknowledging that
you're really desperate to use a web browser as root (when it's not
the safest, secure thing to do) so there are flags that remain as an
advanced avenue to do so.

How to get Caja to work, I don't know because I don't know that
package. Is there a preference menu where you can set it to point to
something else file manager'y comparable?

That's the only thing I can think to do... unless there's an advanced
way under "Preferences" to addend whichever chromium flag will work
under these circumstances.

Hope this helps someone... some day.. :)
