Dmat00's questions

I am running Ubuntu 16.04. I haven't been able to update the software in months because I keep getting this message. I tried switching between servers. That's not it. Tried updating the expired keys. Still no luck. Please help me resolve this. I can't even upgrade to a newer version of Ubuntu to fix it. Nothing works.

I am also wondering if this has to do with the Trust software providers section of the software updated being empty. Here is a screenshot:

Software Updater gives me the following:

Failed to download repository information. Check your internet conntection.

Can't run sudo-apt-get-update. I get this message:

I then tried updating the keys:

for K in $(apt-key list | grep expired | cut -d '/' -f2 | cut -d' '-f1); do sudo apt-key adv --recv-keys --keyserver keys.gnupg.net $K; done 

And output:

Is anyone noticing problems when trying to install rvm on ubuntu? I have both Ruby 1.8.7 and 1.9.2 installed on my machine but can't figure out how to make it default to 1.9.2 other than the rvm route. However, when I go to install rvm using the following command:

bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )

I receive this error message:

Warning: /usr/share/ruby-rvm/archives/wayneeseguin-rvm-stable.tgz: Permission 
Warning: denied
  0  792k    0  2896    0     0   1878      0  0:07:11  0:00:01  0:07:10  128k
curl: (23) Failed writing body (0 != 2896)

Could not download 'https://github.com/wayneeseguin/rvm/tarball/stable'.
  curl returned status '23'.

I looked around for a fix but couldn't locate one. This problem has been bugging me since August.

Any help if much appreciated.

PS. If it is easier to remove 1.8.7, do you suggest I just do that?

Update:

Using sudo apt get.

I almost can't believe what a pain in the a&& it is just to use rvm. After I finally got rvm installed and the bash files working correctly, I went to install ruby version 1.9.2. Of course, the rvm git file has the wrong code as you can read about in this link: https://github.com/wayneeseguin/rvm/commit/52018750763d5321b7b993e201c8589b98e090f9

So here we go again, I opt to use rvm install 1.9.2-head and it installs this version of ruby correctly.

I then tell rvm to use version 1.9.2 with the follow command, rvm use 1.9.2-head. Rvm tells me it is now using 1.9.2. But then when I version check ruby with ruby -v, I find out that it is still using 1.8.7.

Why is it so difficult to get this working? I feel like I've wasted hours on something that should have been relatively easy.

Does anyone know how to properly uninstall Ruby 1.8.7 and install Ruby 1.9.2 on Ubuntu 11.10?

I have thoroughly searched and none of the tutorials I've found have worked.

Also, I spent a very long time trying to get RVM to work and it just is a pain to use. Additionally, I will have little use for the older version.

Update outputs:

which ruby:

/usr/local/bin/ruby

ls -l /usr/local/bin/ruby:

lrwxrwxrwx 1 root root 16 2011-10-17 21:20 /usr/local/bin/ruby -> /usr/bin/ruby1.8

ls -l /etc/alternatives/ruby:

lrwxrwxrwx 1 root root 18 2011-12-30 17:35 /etc/alternatives/ruby -> /usr/bin/ruby1.9.1

echo $PATH:

/usr/lib/lightdm/lightdm:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games

By the way, when I look at --config gem, it tells me that there is only one gem, which is /usr/bin/gem1.9.1
