Build error

The line

repo init -u https://github.com/LineageOS/android.git -b lineage-18.1;

in https://divestos.org/index.php?page=build#init fails.

I have tested it in an empty folder, and same error as below

$ mkdir TESTFOLDER
$ cd TESTFOLDER
$ repo init -u https://github.com/LineageOS/android.git -b lineage-18.1

It looks like a LineageOS bug, is it?

In addition, you might want to update the documentation for building on Ubuntu 18.04:

• the package libesd0-dev is not available in the official repos, but can be obtained by adding the repos

deb-src http://us.archive.ubuntu.com/ubuntu/ xenial main universe
deb http://us.archive.ubuntu.com/ubuntu/ xenial main universe

to /etc/apt/sources.list

• the package libgcc1:i386 is not available on amd64 machines, but can be obtained by adding the i386 architecture

sudo dpkg --add-architecture i386;

• gocryptfs is not available by default

sudo apt install -y gocryptfs;

One may also need to install fuse if it is not installed already.
