Error when updating software with experimental Buster for Pi4

after booting the Pi4 + BrickPy 3, and connecting with VNC, the first thing I have done was to issue

sudo apt full-upgrade

and I got the error:

Errors were encountered while processing:


E: Sub-process /usr/bin/dpkg returned an error code (1)

Ever since, every time I install a new package with apt install , the installation of the package completes, but returns the same error.

It is especially an issue when running installation scripts, such as for ROS, that install multiple dependencies, and after every installation stop reporting that same error, in spite of the fact that the dependency was installed correctly.

Please let me know if I can collect any useful information to troubleshoot the issue.
