bypass ln -s permission denied ? - selfhate - Mar 4, 2017
root~: ln --help
Usage: ln [OPTION]... [-T] TARGET LINK_NAME (1st form)
or: ln [OPTION]... TARGET (2nd form)
or: ln [OPTION]... TARGET... DIRECTORY (3rd form)
or: ln [OPTION]... -t DIRECTORY TARGET... (4th form)
In the 1st form, create a link to TARGET with the name LINK_NAME.
In the 2nd form, create a link to TARGET in the current directory.
In the 3rd and 4th forms, create links to each TARGET in DIRECTORY.
Create hard links by default, symbolic links with --symbolic.
When creating hard links, each TARGET must exist. Symbolic links
can hold arbitrary text; if later resolved, a relative link is
interpreted in relation to its parent directory.
Mandatory arguments to long options are mandatory for short options too.
--backup[=CONTROL] make a backup of each existing destination file
-b like --backup but does not accept an argument
-d, -F, --directory allow the superuser to attempt to hard link
directories (note: will probably fail due to
system restrictions, even for the superuser)
-f, --force remove existing destination files
-i, --interactive prompt whether to remove destinations
-L, --logical make hard links to symbolic link references
-n, --no-dereference treat destination that is a symlink to a
directory as if it were a normal file
-P, --physical make hard links directly to symbolic links
-s, --symbolic make symbolic links instead of hard links
-S, --suffix=SUFFIX override the usual backup suffix
-t, --target-directory=DIRECTORY specify the DIRECTORY in which to create
the links
-T, --no-target-directory treat LINK_NAME as a normal file
-v, --verbose print name of each linked file
--help display this help and exit
--version output version information and exit
The backup suffix is `~', unless set with --suffix or SIMPLE_BACKUP_SUFFIX.
The version control method may be selected via the --backup option or through
the VERSION_CONTROL environment variable. Here are the values:
Using -s ignores -L and -P. Otherwise, the last option specified controls
behavior when the source is a symbolic link, defaulting to -P.
none, off never make backups (even if --backup is given)
numbered, t make numbered backups
existing, nil numbered if numbered backups exist, simple otherwise
simple, never always make simple backups
ln -s : permission denied
ln -b : permission denied
ln -v : permission denied
sudo ln -s : permission denied

Try sudo -i , looks like you are already root but i don't mind anything else.

well a root usually has a "#" before his command line. (you got root~: ; instead root#: ) so i guess only your username is root but you arent in fact. sudo maybe hasnt worked, because "root" is not in the sudoers file. try to check on that.
