I want to run this command (see section 4 from here https://help.ubuntu.com/community/AptGet/Howto#Removal_commands):

dpkg -l | grep '^rc' | awk '{print $2}' | xargs dpkg --purge

I use sudo at the beginning but anyway I get an error:

user@user-desktop:~$ sudo dpkg -l | grep '^rc' | awk '{print $2}' | xargs dpkg --purge
[sudo] password for user:
dpkg: error: requested operation requires superuser privilege

Why sudo doesn’t work? What else should I type?

try to login as root, to gain the super-power, you can do this by typing:

sudo -i

then write (copy/paste :: Ctrl + C / Ctrl + Shift + V <— paste in terminal) your command in terminal, and it should work

sudo only applies to a single command, not the whole pipeline. In your case, the command ran as superuser was dpkg -l – which is not necessary.

On the contrary, the command really requiring the superuser access in your pipeline is dpkg --purge, so prepend sudo directly to it.

dpkg -l | grep '^rc' | awk '{print $2}' | xargs sudo dpkg --purge

By the way, awk can filter rows using regular expressions just like grep does, so you can save one command:

dpkg -l | awk '/^rc/{print $2}' | xargs sudo dpkg --purge

sudo -i dpkg -l | grep '^rc' | awk '{print $2}' | xargs dpkg --purge

This may run your command with ROOT priviliges.
Sudo and root is different. Reference

Nothing to worry about, it’s all normal.

In case you are curious, here is what ‘sudo’ does:

Sudo is a command that can be used as a prefix to other commands in the terminal. It means that you have the authority to give that order even though it’s one that normal users cannot give.

A normal user is not the real administrator; the real administrator is a virtual user called root. A normal / standard user who is an ‘admin’ like you, though, has sudo rights which means that you can say to root: Do this for me, because I have sudo rights. You will then be prompted for your password. This ensures that no one else can do things in your computer which require sudo rights. Only you, and not your roommate, a burglar or someone who is using a guest account. Typically, such things are everything that makes a change to the system, such as installing software.
When you update, for example, you have to enter your password. Because an update is a change to the system.

You could say that by using the terminal, you are having a conversation with root, that goes like this:

You: (gives command) Do this for me.
Root: No, you don’t have authority.
You: (types ‘sudo’ then a command) Do this for me, because I do have the authority.
Root: (asks for password) Is that so? Please prove this by providing your password.
You: (types password) Here it is.
Root: (executes command)

If your issue is solved, kindly indicate that by editing the first post in the topic, and adding [SOLVED] to the title. Thanks!

Ubuntu 15.10 — dpkg: error: requested operation requires superuser privilege

I am trying to install two packages to enable my ethernet and wifi, the commands seems to fail.

dpkg: error: requested operation requires superuser privilege

Below is my network information:

Re: Ubuntu 15.10 — dpkg: error: requested operation requires superuser privilege

Both dpkg commands require elevated privileges.

Re: Ubuntu 15.10 — dpkg: error: requested operation requires superuser privilege

Thanks, it worked but why is it asking for internet connection to install the package, «some problem occured during the firmware download. Please check your internet connection». I am not connected to internet while using the ubuntu [No Ethernet or No Wifi]

Re: Ubuntu 15.10 — dpkg: error: requested operation requires superuser privilege

First things first, i’m going to move your question to the Network and Wireless subforum.

Is this package firmware-b43-installer_019-2_all. trying to download the firmware ?
Do you need both packages ?
What tutorial are you trying to follow ? Do you have a link ?

I’m not the best person to help you with your question as i have never used those two packages but be patient and someone will come along to help you.

E:_cache->open() failed, please report SOLVED.

I am a techno-dumbo, but I’ve searched these forums to no avail. I’m probably asking the wrong questions.

I’ve been trying to do a software update, but it comes up with the following message:

Code: Select all

E:dpkg was interrupted, you must manually run 'dpkg --configure -a' to correct the problem.
E:_cache->open() failed, please report

When I use terminal & enter the instruction to run dpkg as above, I get a message that says:

Code: Select all

dpkg: error requested operation requires superuser privilege.

the updates are for:

Code: Select all

grub2-signed new version 1.167-18.04.3+2.04-1 ubuntu44.1
grub2-unsigned new version 2.04-1ubuntu44.1

I am at a loss to know what to do next. How do I make myself a ‘superuser’ — and is it something I should do?

Hi there,

As the last in a long line of Janners, I thank you for making the trip down here to help from up country. I doubly thank you for not bringing your caravan ;^) .

I’ll give your advice a go when I’ve sobered up & let you know how it went.

I had to look up ‘Janner’ — nice one. Sadly we don’t seem to call ourselves anything that’s printable, ‘cept for us being: Crousty, Tilty, Tinklebobs, Torrididdle or even Twanketen.

I loved that you said ‘I’ve no idea what I’ve just done’, because I’ve no idea what that command does either :shock: I’ve just learnt, through rote, that it works.

In case you are curious, here is what ‘sudo’ does:

Sudo is a command that can be used as a prefix to other commands in the terminal. It means that you have the authority to give that order even though it’s one that normal users cannot give.

A normal user is not the real administrator; the real administrator is a virtual user called root. A normal / standard user who is an ‘admin’ like you, though, has sudo rights which means that you can say to root: Do this for me, because I have sudo rights. You will then be prompted for your password. This ensures that no one else can do things in your computer which require sudo rights. Only you, and not your roommate, a burglar or someone who is using a guest account. Typically, such things are everything that makes a change to the system, such as installing software.
When you update, for example, you have to enter your password. Because an update is a change to the system.

You could say that by using the terminal, you are having a conversation with root, that goes like this:

You: (gives command) Do this for me.
Root: No, you don’t have authority.
You: (types ‘sudo’ then a command) Do this for me, because I do have the authority.
Root: (asks for password) Is that so? Please prove this by providing your password.
You: (types password) Here it is.
Root: (executes command)

Through ‘rote’ I ‘knew’ that the ‘sudo configure …’ command would work, but understanding ‘why’ is great.

Only problem is that my computer now talks to me – do I need even more medication?

SCRUMPY!

Scrumpy won’t touch that. Lidl do a Napoleon XO brandy called ‘Reverie’ at an amazingly good price. It does exactly what it says on the label. I commend it to you ;^) .

Запуск Ubuntu версии 13.04 и вход в систему как администратор и говорит, что мне нужен суперпользователь для запуска dpkg, я думал, что admin является суперпользователем. Что я делаю неправильно?

Вам все еще нужно использовать sudo для повышения установки dpkg, do:

sudo dpkg -i vzaccess-7.5_2766f-1ubuntu1110.deb

, затем введите свой пароль пользователя.

  2. Re: Ubuntu 15.10 — dpkg: error: requested operation requires superuser privilege

    Hi

    Try this

    Code:

    sudo dpkg -i b43-fwcutter_019-2_1386* && sudo dpkg -i firmware-b43-installer_019-2_all*

    Both dpkg commands require elevated privileges.

    Kind regards

  3. Re: Ubuntu 15.10 — dpkg: error: requested operation requires superuser privilege

    Thanks, it worked but why is it asking for internet connection to install the package, «some problem occured during the firmware download. Please check your internet connection». I am not connected to internet while using the ubuntu [No Ethernet or No Wifi]

    First things first, i’m going to move your question to the Network and Wireless subforum.

    Is this package firmware-b43-installer_019-2_all… trying to download the firmware ?
    Do you need both packages ?
    What tutorial are you trying to follow ? Do you have a link ?

    I’m not the best person to help you with your question as i have never used those two packages but be patient and someone will come along to help you.

    Kind regards
