BTW, do not confuse the pkgconfig python package and the pkg-config commandline tool (which is required and used by the python package).

Okay thank you but what dependencies can I be missing? as I just went through them all again and I am sure all of them are installed after checking my system

[ThomasWaldmann]

apt install pkg-config

[Solverz-0]

apt install pkg-config

Can these dependencies not be installed in the Virtualenv? (Sorry if this obvious question)

Or is the Virtualenv just for python libraries?

[ThomasWaldmann]

No, that is not a python software package, but ubuntu provides it as a .deb package. a virtual env is only for python software.

pkg-config is a tool which is generally useful to locate libraries and headers (borg uses it to find the zstd, lz4, openssl, xxhash stuff).

[ThomasWaldmann]

Did you get it working?

[ThomasWaldmann]

Well, let's assume so.
