How can I execute program from other user UBUNTU 18.04?

masteritua · March 23, 2021, 4:03pm

How can I install program from other user?
su - test
sudo apt-get update
sudo: effective uid is not 0, is /usr/bin/sudo on a file system with the ‘nosuid’ option set or an NFS file system without root privileges?

Hi @masteritua,

Can you say a bit more about how you got to that error? Is this an Ubuntu container deployed via a 3Bot or through a VDC?

I’m not sure if it’s possible to change the ‘nosuid’ option in either case. Perhaps installing packages as root would work just as well?

I use solution - Ubuntu container deployed via a 3Bot

I have also other error, when I try to execute comand down:

NO, I got the errors above!

Try using a larger root disk size for your ubuntu image.

From my 3bot I deployed 18.04 with root disk size ~ 20GB

Also @masteritua I don’t think you can install docker in non-privileged containers

but for your question to allow sudoers to install packages: I also don’t think the filesystem supports suid nor cap admin, @azmy @maxux42 any idea?

azmy · March 25, 2021, 8:20am

If I get your question correctly, you are asking if you can do apt-get install a pkg with the test user. The answer is that you can’t. Only root users can install packages, hence I am wondering why is the reason you try to su - test before u run the apt-get command.

If you really want to do so then what u need to do is the following:

this of course depends on the flist used. I assume you use the ubuntu solution

as root, first make sure the sudo pkg is installed
configure the /etc/sudoers to give the specified user the permission to run apt-get (out of scope of this forum, but there are many resource online)
make sure the setuid flag is set on the sudo file. (that’s the error that is shown in your message) this should be easily done (as root) by doing chmod u+s /usr/bin/sudo.
now switch to the needed user with su - test
as this user you should be able to do sudo apt-get install <pkg> if everything is configured correctly.

I hope this will help

Geert · March 25, 2021, 9:33am

Pleasd bear in mind that you can also create an extra 3bot with admin rights on your 3bot. Then someone else can run the dashboard on your behalf.

scott · March 25, 2021, 8:06pm

I’ve tried running Docker in an Ubuntu container like this. Install works, but attempting to run containers gives an error.

@masteritua, if you need to run containers on the Grid, there’s a way to convert Docker images to native flist images using the flist hub. Another option is to deploy them via Kubernetes inside an eVDC (still on testnet).

masteritua · March 28, 2021, 5:13pm

I have interesting problem:

What I did:

Remove old container Ubuntu from 3bot
Create a new 3bot container UBUNTU 18.04 with params: 10 GB memory and root file

Which characteristics I got in a new container UBUNTU, although must be 10 GB
root@cluster05:~# free -h
total used free shared buff/cache available
Mem: 188G 1.4G 184G 821M 2.7G 185G
Swap: 0B 0B 0B

Why when Do I execute command in new container Ubuntu, I have this problem yet:

dpkg: error processing package libc-bin (–configure):
installed libc-bin package post-installation script subprocess returned error exit status 134
Errors were encountered while processing:
libc-bin
E: Sub-process /usr/bin/dpkg returned an error code (1)

Very interesting!!!
When I want looking history, I got it from old container UBUNTU ???

root@cluster05:~# history
1 apt-get update
2 apt-get install -y openssh-server
3 apt-get install vim
4 vim start.sh
5 ls
6 vim /etc/apt/sources.list
7 apt install docker
8 docker ps
9 docker
10 apt upgrade
11 history

How to full update container UBUNTU ?

scott · March 30, 2021, 8:05pm

Note that commands like free and df are going to show you information about the node your container is running on, not just resources allocated to your container.

As for the history, those first six lines are an artifact from when the container image was created. They show when I deploy Ubuntu as well. If you’ve executed the commands after #6 in this new container, then that’s all normal.

I tried the same steps and wasn’t able to reproduce your error. apt-get upgrade completes without issue. For reference, here is how I set the container resource allocation:
