Error, do this: mount -t proc proc /proc

I am getting this error both on pushes from local to remote and when starting a bash console on PA.

I have been away from PA for a while, but I don't think I've seen this error before.

What happens if you try to just ssh in without the git push?

Staff conrad | 4232 posts | PythonAnywhere staff | Aug. 13, 2016, 2:41 p.m. | permalink

The ssh works fine, but I get that same "proc" error msg. Here are the last few lines of verbose output for the ssh command ssh -v stevetone@ssh.pythonanywhere.com:

That sounds like maybe your bashrc or something is doing something that requires proc. Did you recently add something to your bashrc? (since that will get run upon ssh-ing in)

Traditionally, you could never access /proc

Staff conrad | 4232 posts | PythonAnywhere staff | Aug. 13, 2016, 5:23 p.m. | permalink

I do not think I have ever edited the default .bashrc file. At least not recently. Here it is:

# Load up standard site-wide settings.
source /etc/bashrc
source virtualenvwrapper.sh
SSH_ENV=$HOME/.ssh/environment
# start the ssh-agent
function start_agent {
    echo "Initializing new SSH agent..."
    # spawn ssh-agent
    /usr/bin/ssh-agent | sed 's/^echo/#echo/' > "${SSH_ENV}"
    echo succeeded
    chmod 600 "${SSH_ENV}"
    . "${SSH_ENV}" > /dev/null
    /usr/bin/ssh-add
}
if [ -f "${SSH_ENV}" ]; then
     . "${SSH_ENV}" > /dev/null
     ps -ef | grep ${SSH_AGENT_PID} | grep ssh-agent$ > /dev/null || {
        start_agent;
    }
else
    start_agent;
Beloved premium user stevetone | 10 posts | Aug. 13, 2016, 5:39 p.m. | permalink

There is a "ps" command in that .bashrc. That appears to be generating the error message.

Is there a default .bashrc that I should have?

Beloved premium user stevetone | 10 posts | Aug. 13, 2016, 5:45 p.m. | permalink

I setup a free new account and copied the .bashrc from there. Problem solved :)

Beloved premium user stevetone | 10 posts | Aug. 13, 2016, 6:11 p.m. | permalink

I'm seeing this error when I run pipenv install in my bash console here on Pythonanywhere.

deleted-user-3648138 | 21 posts | Dec. 5, 2018, 11:22 p.m. | permalink

Yes, it looks like pipenv doesn't work with our virtualization system right now :-(

Staff giles | 11800 posts | PythonAnywhere staff | Dec. 6, 2018, 10:06 a.m. | permalink

FWIW, I see that error, but apart from that, it seems to play nicely with my virtualenv, and actually installs what I ask it to.

deleted-user-3648138 | 21 posts | Dec. 6, 2018, 6:46 p.m. | permalink

Interesting! Maybe the sandboxing system is only causing problems with a non-essential feature of pipenv. We'd love to know how you get on with it.

Staff giles | 11800 posts | PythonAnywhere staff | Dec. 8, 2018, 5:42 p.m. | permalink

I am seeing this, just running ps -ef. I moved .bashrc over to bashrc.org, logged in again, and still see this error. I wonder if something has changed

Beloved premium user johnedstone | 2 posts | March 13, 2019, 2:59 p.m. | permalink

No, nothing has changed. ps will still not work and if your bashrc is not running it, then something must be. Examine the error that you see to see if you can work out what is running the command that is causing the error.

Staff glenn | 9498 posts | PythonAnywhere staff | March 13, 2019, 6:53 p.m. | permalink

I saw this error using pipenv as well. I'll let you know if it causes any issues running web2py.

Any idea of the cause and whether it will get resolved? Is it really a non-essential feature of pipenv that I don't need to worry about?

hansonec | 1 post | May 8, 2019, 3:34 a.m. | permalink

We're not sure right now if it's a non-essential feature, but none of the people who have mentioned that they got the error, but continued to use pipenv, have told us that things were broken, so that's a reasonable indication that it's probably not essential.

We don't currently have a timeline on adding /proc support, but it's something we're looking into.

Staff giles | 11800 posts | PythonAnywhere staff | May 8, 2019, 12:29 p.m. | permalink

Whenever I run a pipenv command it shows this error

Error, do this: mount -t proc proc /proc

Error, do this: mount -t proc proc /proc

Then it moves on to doing whatever it was supposed to do.

deleted-user-4779929 | 2 posts | June 7, 2019, 4:48 p.m. | permalink

Do you notice a difference in the output from running it locally? Perhaps it's trying to report something and when it fails at that, it just carries on.

Staff glenn | 9498 posts | PythonAnywhere staff | June 7, 2019, 4:57 p.m. | permalink

Hello, I’m having the same issue here: 

Error, do this; mount -t proc proc /proc

Also when I use the pipenv command.

I’m just getting into this thread in order to receive updates about this post.

deleted-user-6492380 | 1 post | Nov. 18, 2019, 3:03 a.m. | permalink

Cool. We are currently working on a change that will fix this and hope to release it soon.

Staff glenn | 9498 posts | PythonAnywhere staff | Nov. 18, 2019, 1:31 p.m. | permalink

Given that I just encountered this issue for the first time today I'm assuming it was never resolved! Occurred for me while setting up CD which involves SSH to PA server and then running things which include several pipenv run commands. Doesn't seem to be an issue for me so I'm not worried about it, just thought I'd report it.

If anyone else is getting this through SSH and just wants to silence these lines, you need to pipe the stderr from the ssh command into stdout and then grep the error out:

ssh me@ssh.pythonanywhere.com "pipenv run python test.py" 2>&1 | grep -v "Error, do this: mount -t proc proc /proc"
Beloved premium user oliverr | 1 post | Sept. 9, 2021, 3:39 a.m. | permalink

Thanks, that's useful! We've done changes that address the issue in non-SSH, non-Jupyter notebook sessions -- so, in consoles on our site, website code, scheduled and always-on tasks -- but SSH is proving a little trickier, so that's a good workaround to have in the meantime.
