I understand this is a Debian problem, not a TDE problem, however:
On one machine I have installed Debian Stretch + TDE; no problem.
On the same machine I installed (on another partition) Buster + TDE. Seems to
work, however most commands don't work from konsole with su.
The reason is that the path does not contain important directories.
Now the following I don't really understand:
The path is ok in the different files I could check.
I've added "export
PATH=/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
to /root/.profile but it does not work.
The result is that a command such as dpkg -i or dpkg-reconfigure does not
work, until I issue the export PATH= directly in konsole
Debian is fresh installed with netinstall. This is really inconvenient, so of
there is no way to cure it I'm going back to Stretch.

Ran into the same thing. Looks like when changing to root via "su", the
environment and path is from the users .profile, which does not include /sbin (any
more?)

Just after posting I found an "answer" that's more a puzzle to me but does
provide a solution.
Seems Buster changed the package providing su. I found this on StackExchange:
"Note that according to Debian Wiki, previous versions of Debian used a
version of su from the shadow source package, while Buster uses one from the
util-linux sources, which won't auto-add the /sbin and /usr/sbin directories
to PATH when switching to root. If you need to approximate the old behavior,
you can set ALWAYS_SET_PATH yes in /etc/login.defs. – telcoM Jul 6 at 20:23"
Some other place I read that "using su is bad" so we should now use "su
-" to
get a clean environment every time. ?!? . I allready never understood why
using sudo would be better than using su, now this stuff about environment
does not make sense to me either.
Anyway, for those of us using su and not wanting to change the way we use it,
just add ALWAYS_SET_PATH yes in /etc/login.defs and everything is fine.

I discovered the same thing. The solution I use is to always launch su
with "-",
so, "su -"
or "sudo su -"
That loads the complete su profile. It also changes to the /root
directory, which is annoying.
Every Debian update, there's always _something_!

The environment thing is mostly about making sure that environment variables
that are set by your user and not by root don't leak into root's environment.
99% of the time the leaking variables are harmless, but they can occasionally be
the source of some weird and subtle bugs. So typing the extra " -" may save you
days or weeks of wrangling on mailing lists/message boards/reddit/whatever.
As for sudo being better than su, well, it isn't. It just presents a different set
of security and convenience tradeoffs.
