Hi, For the first error, try looking for postfix: ``` apt update apt-cache madison postfix ```
If the first command returns nothing then, postfix is available in the following repositories: ``` http://deb.debian.org/debian buster/main amd64 Packages http://deb.debian.org/debian buster/main Sources ``` Please add them in your sources and try again. For the second problem, try updating pip: ``` sudo python -m pip install --upgrade pip ``` Best, Ajay Tripathi -- You received this message because you are subscribed to the Google Groups "OpenWISP" group.
