I am trying to install  on the ubuntu server 16.04 LTS.   for that I have created file /etc/apt/sources.list.d/mongodb-org-3.2.list and added a line as per the doc.  echo "deb http://repo.mongodb.org/apt/ubuntu xenial/mongodb-org/3.2 multiverse" | sudo tee /etc/apt/sources.list.d/mongodb-org-3.2.list   Now when I try to download the package list using sudo apt-get update it is giving me below error.  nodev@ubuntu:/etc/apt/sources.list.d$ sudo apt-get update E: Type 'echo' is not known on line 1 in source list /etc/apt/sources.list.d/mongodb-org-3.2.list E: The list of sources could not be read.

Every once in a while I see users having issues to update due to errors like this:  E:Type 'ain' is not known on line 1 in source list /etc/apt/sources.list.d/some-ppa.list'   with varying types/line numbers/source list files (often after removing a PPA).  How can such an error be fixed?

How do I install the latest  on Ubuntu? I've been looking around, and I can't find anything. Is there a Ubuntu package for node.js, or do I have to compile it myself?

I'm unable to update nodejs, and I can't see why.  If I were to make a guess, I'd say that I have two repositories listed in apt-get, that both contain a nodejs package.  Here's what I've done:  Remove old version:  sudo apt-get remove --purge nodejs npm   Then, going by , I've run:  curl -sL https://deb.nodesource.com/setup_5.x | sudo -E bash -   And then:  sudo apt-get install -y nodejs   I then run:  nodejs -v   Which returns:  v0.10.25   Can anyone explain what's going wrong? And how I can remedy this situation?  Many thanks.

I have 20 to 3o computers on my network and I have a copy of the debian packages on /var/cache/apt/archives but when I take this downloaded copy to any other machine I need to hit an "apt-get update" , How do I avoid this ? Where is the list of packages which is updated by that command stored. I need to copy them as well, and use it on a computer which is completely offline.

I'm a new user of Ubuntu 13.10.  I recently tried to resolve a Skype installation issue and added some PPA involving binary-1386.  Every time I run sudo apt-get update, I get the following error:  W: Failed to fetch http://archive.ubuntu.com/ubuntu/dists/saucy/Release  Unable to find expected entry 'restricted/binary-1386/Packages' in Release file (Wrong sources.list entry or malformed file) W: Failed to fetch http://extras.ubuntu.com/ubuntu/dists/saucy/Release  Unable to find expected entry 'main/binary-1386/Packages' in Release file (Wrong sources.list entry or malformed file) ... ... E: Some index files failed to download. They have been ignored, or old ones used instead.   I have spent the last two hours trying to resolve this issue, and made changes to my sources.list file by resetting to.the default saucy settings, but these errors are still occuring.  I've also unchecked everything in Software and Updates section, but this still seems to appear.  The error messages seem to be related to the 'binary-1386/Packages' in Release file (Wrong sources.list entry or malformed file) issue as shown above.

I tried installing VLC Player yesterday, and I got the Requires installation of untrusted packages error.  I searched for hours for a solution to this problem, and finally came upon a suggestion that said to change servers for downloading updates from.  I did this, and it gave me a 404 error when I clicked on "Check" in the Update Manager.  I tried switching my server back to the main one (and after that, several other ones), but I am now still getting a 404 error:   And the other error I get when downloading or updating:   Edit: Output of cat /etc/apt/sources.list:  deb-src http://us.archive.ubuntu.com/ubuntu/ precise main restricted #Added by software-properties  # See http://help.ubuntu.com/community/UpgradeNotes for how to upgrade to # newer versions of the distribution. deb http://us.archive.ubuntu.com/ubuntu/ precise main restricted multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ precise multiverse universe #Added by software-properties  ## Major bug fix updates produced after the final release of the ## distribution. deb http://us.archive.ubuntu.com/ubuntu/ precise-updates main restricted multiverse deb-src http://us.archive.ubuntu.com/ubuntu/ precise-updates restricted main multiverse universe #Added by software-properties  ## N.B. software from this repository is ENTIRELY UNSUPPORTED by the Ubuntu ## team.

I have deleted some files around /var/lib/dpkg/, namely:  /var/lib/dpkg/status /var/lib/dpkg/available /var/lib/dpkg/info/*   I understand Debian uses these files to keep some information about installed packages. Now when I do apt-get update, I get following error:  Reading package lists... Error! E: Could not open file /var/lib/dpkg/status - open  (2: No such file or directory) E: The package lists or status file could not be parsed or opened.   As I understand the , files located in /var are not supposed to be system-critical. Rater these should be temporary files, logs, caches, and similar.   Is there therefore a way to recreate the deleted files ?

FreeBSD user joining your ranks.  I've been asked to look after an Ubuntu Server running 10.04 LTS.     I see from /usr/lib/update-notifier/update-motd-updates-available that there are a number of updates on the server however I do not see a way to tell which will be updated.  Would anyone be able to point me in the right direction so as I can see which packages will get updated when I run apt-get upgrade?  UPDATE:  Can't answer my own question at the moment so throwing this in here for the time being:  Along with the apt-get upgrade --dry-run suggested below,  /usr/lib/update-notifier/apt-check -p will list all packages that have updates available.
