Unable to connect to postgresql with pgAdmin4: readonly attribute error

Question

I have a local postgresql 10 server (tested the same on 9.6, don't think it's related to the DB at all, only to pgAdmin4, as pgAdmin3 works just fine)

As in the screenshot, I am trying to connect to the localhost db with user postgres on a fresh installation, but I keep receiving this message:

readonly attribute

I searched everywhere for this error, but couldn't find any useful solutions or workarounds

Answer 1

pg4Admin 4 now is working for me. I got an update of python-psycopg2 to 2.7.4-1.pgdg16.04+1 amd64 version on my KDE Neon, that solved, to me, the readonly attribute problem.
