Maybe you should reboot before researching and such as installing sudo.
It is supposed to be there.

In the meantime, see if it is there:

type -a sudo

I did reboot , and I googled the problem but nothing worked:

Did you try passing some commands like: "sudo reboot" or "sudo shutdown
-r now"

Probably you need to apply some valid commands. A command such as "su
sudo" is going to fail.

You said "copied back my documents"... Okay post results of:

Maybe when you copied your documents you disable your user default path

But how or why would that happen ?

This is likely a new install, where the /home was
copied from elsewhere after the install finished.

Step one: Install Ubuntu (on SSD)
Step two: Copy old /home/robh (on RAID1 pair) to new /home/robh (on SSD)

We don't know if the new install is "robh" as
well as the old home being "/home/robh" and the
/etc/passwd matching and so on. The /etc/sudoers
doesn't seem to have the account-specific details
you might find on a Unix workstation (as done by an IT guy).

Defaults secure_path="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/snap/bin"

# User privilege specification
root ALL=(ALL:ALL) ALL

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo ALL=(ALL:ALL) ALL

Johnathan suggested

echo $PATH

and a person could also try

which sudo

to see if it is in the path (or some path variable)
or not.

On more modern setups, I can no longer tell
via looking at dot files, where the hell the $PATH
comes from :-) All the details don't seem to be
spelled out in the user /home/username/.xxx area. They must
be coming from /etc or something.

nitpick: the syntax is correct, there's just no file with that

you need a slash before the 'usr/bin/sudo' as in

Or a

Check your umask value, and see if it is interfering.
Mine is 0022 (the lead zero presumably is for SUID or something).
Traditionally it would have printed out 022, and not interfered
with a 755 incoming.

$ umask
0022 # 755 packed ==> 755 unpacked, should have worked

It's like a .profile or similar, is not working. Like, maybe, when
you copied home, some dot files got missed ? Anyway, check umask.

This stuff happens all the time, when unpacking kits like this.
It doesn't even require shenanigans to break it :-)

You problem isn't related to sudo here.
If you run shell scripts, you have 2 options:
You can either rund them directly, by ./script.sh, but here it is
necessary that the executable bit for the user running is set (be ware
of the context, owner, group others).

The other option is to use the bash command and use the path to the
script as option:
bash ./script.sh
This doesn't require that the x bits are set. It requires that you can
read the file (r bit).

Since sudo is installed you can use it with other commands as well.

You are confusing that with file permissions that are a separate
topic. If the file owner defines a file as non writable, then he
cannot just overwrite it. The user defined it to be non-writable,
and if he wants it differently he can change the file permissions.

I am Administrator in users and groups with a password which works
everytime. So if I am an administrator, why am I getting this error.

Should be obvious already from many of the replies; re-read them.

Octal representation of '...rwxrwxrwx' clearing the rightmost 'w' so
that you get 'rwxrwxr-x' (others may not write the file).

"umask sets the file creation mask of the current shell execution
environment to the value specified by the mask operand. This mask
affects the file permission bits of subsequently created files.
mask can either be an octal number or a symbolic value as described
in chmod(1). If a symbolic value is given, the new file creation mask
is the complement of the result of applying mask to the complement of
the current file creation mask."

That time you got the syntax wrong;

nitpick: the syntax is correct, there's just no file with that

you need a slash before the 'usr/bin/sudo' as in

/usr/bin/sudo

Or a

cd /

So you wouldn't call the 'missing' leading slash a syntax error, given
the relative path?

Wrong. It calls bash and bash runs the script in the first argument. It
will not "install" that script anywhere.

As I've shown in the second example (the one with 'cd /'), the same
construct (with the same syntax) is working just fine. So, yes, it's
not the syntax that is wrong, it's the semantical context.

Anyway it was just a nitpick, likely not worth for a discussion in a
thread with a very practical question. Though if you're interested to
discuss that (lexical components, syntactical phrases, and semantic
contexts in the shell language) we can of course expand on that, but comp.unix.shell might be a better place for that.
