I think this can be solved by declaring Conflict with openpcd which would force de-install of it, see https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts

I'm not sure if Replaces is better choice, but I would not expect to have both packages installed, so I'm removing openocd manually before toolchain install.

debian package is created with alien. Alien does not support that field.

Only way I can see that it can be done is to create custom debian/ packaging.

Workaround for this is to remove openocd from the Debian:

apt-get remove --purge openocd

and then to install ulx3s package.
