Repo init error when accessing Angstrom repo


I have a problem to get an Angstrom repo. I’m using ubuntu 21.04.

The last fatal was raised in python module line 1386:

# |src| is the file we read from or path we point to for symlinks.
# It is relative to the top of the git project checkout.
is_linkfile = element == ‘linkfile’
msg = cls._CheckLocalPath(src, dir_ok=is_linkfile, cwd_dot_ok=is_linkfile)
if msg:
raise ManifestInvalidPathError( <— Line 1386
‘<%s> invalid “src”: %s: %s’ % (element, src, msg))

It seems that anything with the symlink is wrong. But why?
