Ruby RVM apt-get update error

Question 1

RVM doesn't behave well if apt-get update has errors. If your apt sources have an invalid repository that gives 404 or GPG error, RVM will refuse to work. This can be confusing because it happens even if the faulty repository has nothing to do with ruby or RVM.

The following fix worked for me (Ubuntu):

Run apt-get update and see if there are any errors. Edit your sources.list and precise.list in /etc/apt to remove the faulty repositories. Repeat until apt-get update succeeds without any errors. Then try running RVM.

Question 2

You can try to skip the rvm updating system so apt-get won't be called.

# Disable RVM from trying to install necessary software via apt-get
rvm autolibs disable

# Then try installing Ruby:
rvm install 2.4.0

See https://stackoverflow.com/a/16759839/1212791

Question 3

I also had to remove failing repositories but I had hard time spotting them and removing them based on instructions here. So I found this link which explains exactly why this happens and how to remove failing repositories:

In short, run following to find failing repositories:

sudo apt-get update | grep "Failed"

An example output can be like this:

:~# apt-get update  | grep "Failed"
W: Failed to fetch http://ppa.launchpad.net/upubuntu-com/web/ubuntu/dists/trusty/main/binary-amd64/Packages  404  Not Found

W: Failed to fetch http://ppa.launchpad.net/upubuntu-com/web/ubuntu/dists/trusty/main/binary-i386/Packages  404  Not Found

E: Some index files failed to download. They have been ignored, or old ones used instead.

And finally use this command to remove the failing repo(s):

sudo add-apt-repository --remove ppa:{failing ppa}

for the example here it will look like this:

sudo add-apt-repository --remove ppa:upubuntu-com/web

Question 4

Alternative, it is also possible to cut the crap in rvm. I edited requirements_debian_update_system() in file /usr/share/rvm/scripts/functions/requirements/ubuntu like this:

  requirements_debian_update_system()
  {
  echo "*fake* apt-get update"
  #  __rvm_try_sudo apt-get --quiet --yes update ||
  #  {
  #    typeset __ret=$?
  #    case ${__ret} in
  #      (100)
  #        rvm_error "There has been error while updating 'apt-get', please give it some time and try again later.
  #404 errors should be fixed for rvm to proceed. Check your sources configured in:
  #    /etc/apt/sources.list
  #    /etc/apt/sources.list.d/*.list
  #"
  #        ;;
  #    esac
  #    return ${__ret}
  #  }
  }

Question 5

This happened to me as well when I was trying to install a version of Ruby as a non-sudoer user. However, when I logged in as my admin user (with sudo privileges) and ran sudo apt-get update | grep "Failed" I would get no errors and, yet, rvm install x.x.x would still result in asking for a password (when I ran rvm install as the non-sudoer user.)

I was banging my head with this for a while because I didn't want my rvm (regular user) user to have sudo privileges. Then after some putzing around on Google I figured out that I could log in as my admin user.

Go through the steps of installing RVM for that user (as per their documentation):

$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

$ \curl -sSL https://get.rvm.io | bash -s stable

$ source ~/.rvm/scripts/rvm

Then (as the admin user) jump straight into installing the RVM required packages:

$ rvm requirements

at which point it asks for my sudo password and installs the required apt packages for the entire system after I enter my password.

Then I log off from server as admin user and log back in as rvm user (with no sudo privileges) and try to install a version of Ruby.

$ rvm install x.x.x

and now it works.

Question 6

You don't need of apt-get to install rvm and to use it !

Just curl (apt-get install curl)

Launch \curl -sSL https://get.rvm.io | bash -s stable --ruby

and rvm install 2.1.1 or another ruby's version and it works ;)

gem update etc...

RVM will be independent of apt-get so you'll have no longer issu.

Question 7

I had the same issue. If none of the other answers work try this. I ran the following command to fix it:

sudo apt-get -f install

Then I remembered that I failed installing a package earlier that day. What this command did was resolve the dependencies on that package and allowed RVM to do its thing.

Question 8

I just tried

sudo apt-get update and found some of them are failing; for example..

Err http://extras.ubuntu.com raring/main Sources 404 Not Found

I went ahead and deleted those items from the list here..

sudo gedit /etc/apt/sources.list

It worked!

Question 9

I was getting an error similar to this while running curl -sSL https://get.rvm.io | bash -s stable --ruby. It took a while but I finally realised that I had synaptic open: the installer couldn't run because apt was locked

Question 10

I was also getting this error when my working directory was inside a mounted dir.

The fix was just to:

cd ~

I figured this out by seeing this at the bottom of a sudo apt-get update

E: Unable to change to /path/to/my/current/directory/ - chdir (13: Permission denied)

Question 11

I got the same error.I tried most of above answers but none works for me, so i just change server

Goto directory etc/apt
click on Sources.list
Change the server to us or some else server
Reload (it will update your cache from that server)
Then run sudo apt-get update

Question 12

this problem caused in apt-get update so you have to disable the PPA :

System Settings>Software & Updates>Other Software

then reinstall.

Question 13

In my case rvm missed some linux packages, which couldnt be installed without sudo. There were no apt-get install errors at all.

When running rvm install ruby x.x.x with sudo, rvm installed packages required to build ruby and it worked.

Question 14

Issue - requirements_debian_update_system ruby-2.2.2 error

I also had the same issue. I found info on this link Click Here

I followed this and resolved my issue. Was able to install ruby as

rvm install 2.2

Question 15

1) Before installing ruby must be done update:

apt is preferred over apt-get for interactive use in recent Ubuntu versions and apt should fix by:

sudo apt update
sudo apt upgrade

Or with apt-get may be used --allow-releaseinfo-change

sudo apt-get --allow-releaseinfo-change update

2) After successfully installation, for example ruby-2.3.1:

rvm install 2.3.1

Question 16

apt install libc6:amd64 libc6:amd64 libc6 libc6-dev:amd64 libc6-dev libc-dev-bin libc-bin man-db libc-dev-bin libc6-dev:amd64

thats work fine for me ^^

Question 17

The problem is with your sources configured in:

/etc/apt/sources.list
/etc/apt/sources.list.d/*.list

So to check the errors you have to run this command and need to find that which PPA is firing errors:

sudo apt-get update | grep "Failed"

Then to resolve this error you have to press the Windows key and need to search "Software & Updates".

Then open it and go into Other Software there you can see some URLs which is failed while update.

Then uncheck those URLs from this and close this window and then do

sudo apt-get update

Finally, you can install ruby with

rvm install 2.4

PS: You can change the version you want to install ruby.
