having trouble installing borg using pip

[sunhasgothishaton]

Hi

I tried to install borg 1.2.0 on ubuntu 20.04 LTS and got the following error, what can I do? I'm new to pip and installing pip/python packages.

pip3 install "borgbackup==1.2.0"
Defaulting to user installation because normal site-packages is not writeable
Collecting borgbackup==1.2.0
Using cached borgbackup-1.2.0.tar.gz (4.0 MB)
Preparing metadata (setup.py) ... error

Fantastic, thank you. Got it working.

Closing this as outdated: it has seen no activity for a long time and predates the current borg releases.

If this still affects you on a current version - borg 1.4.x (stable) or the borg 2.0.0 beta - please open a new discussion with up-to-date details.
