Effective the turn of this year the Synaptic Package Manager for Lubuntu 14.04 on ALL my computers STOPPED WORKING!!! (I have 5 computers, all with matching Lubuntu OS's.)

I still get updates of a sort--that's all.

I cannot reload without errors like the following:

Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/Release Unable to find expected entry 'universe/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file) Failed to fetch http://archive.ubuntu.com/ubuntu/dists/trusty/main/binary-i386/Packages Hash Sum mismatch Some index files failed to download. They have been ignored, or old ones used instead.

I get similar readings on ALL my computers.

I really do NOT want to have to find a new OS that will work on ALL my comps--it took me too long to find Lubuntu. PLEASE HELP!!!!!!

I tried to post it, but this forum considers my reply to be "links" and will not let me post it--I used the Ubuntu Repository Generator (very carefully, I'm no novice).

Afterwards I had far less errors, but still errors--the errors I have left were in the ORIGINAL install!!!

I have scoured the Net for the past 3 weeks trying to find an answer--NOTHING!!!

OK, I have copied what you sent into the repo list (deleting everything that was there FIRST)--(I know what I am doing here--just not how to solve my problem)

After I did that I ran sudo apt-get update--this was what came up;

Failed to fetch http: //us.archive.ubuntu.com/ubuntu/dists/trusty/Release Unable to find expected entry 'restricted/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file)

Failed to fetch http: //us.archive.ubuntu.com/ubuntu/dists/trusty/main/binary-i386/Packages Hash Sum mismatch

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

REMEMBER I copied exactly what you sent and put it in the file all by itself and this is what I got......

UPDATE: I partially solved the problem, but still have the problem....

I went to Repositories in Synaptic and un-checked "Community-maintained free and open-source software (universe)" then un-checked "Proprietary drivers for devices (restricted)" then also, "Software restricted by copyright or legal issues"

THEN, I ran update again--this is what I got left:

Failed to fetch http: //us.archive.ubuntu.com/ubuntu/dists/trusty/main/binary-i386/Packages Hash Sum mismatch Some index files failed to download. They have been ignored, or old ones used instead.

There is NOT MUCH left to UN-CHECK!!!!!

Now your beginning to see my problem--where do I look to find this "binary" thing and get RID OF IT?!

NEW UPDATE-- I copied my repository list...

deb http: // us .archive.ubuntu.com/ubuntu/ trusty main

deb http: // us .archive.ubuntu.com/ubuntu/ trusty-updates main

deb http: // security .ubuntu.com/ubuntu trusty-security main

deb http: // archive.canonical.com/ubuntu trusty partner

deb-src http:// archive.canonical.com/ubuntu trusty partner

When I try to update I get the following:

Failed to fetch http: // us.archive .ubuntu .com/ubuntu/dists/trusty/main/binary-i386/Packages Hash Sum mismatch

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

QUESTION--I need to know WHERE to look for this erroneous data so I can DELETE IT!!!

NEW INFORMATION: On the advice I found elsewhere I ran the following--I don't know what this means, but I think you might....

x@x-Inspiron-8600:~$ ping -c 3 www.ubunu.com PING www.ubunu.com (69.172.201.208) 56(84) bytes of data.

Try this, it seems to have the same problems and a solution "The following signatures were invalid: BADSIG 16126D3A3E5C1192". The probles seems to be that it does not want to run the equivalent of sudo apt-get update as it cannot verify the found files. – Wilf Mar 14 '15 at 23:51
    
Fixed that and now this-- Failed to fetch archive.ubuntu.com/ubuntu/dists/trusty/Release Unable to find expected entry 'universe/binary-i386/Packages' in Release file (Wrong sources.list entry or malformed file) Failed to fetch archive.ubuntu.com/ubuntu/dists/trusty/main/binary-i386/… Hash Sum mismatch Some index files failed to download.

Could you edit into your question the output of cat /etc/apt/sources.list? – Wilf Mar 15 '15 at 0:12
    
I do not have the word "binary" anywhere in my /etc/apt/sources.list. I'm also on Lubuntu 14.04. – DK Bose Mar 15 '15 at 1:53

"malformed file" is a syntax error. You need to check your /etc/apt/sources.list file and check the error message again as it should specify the exact line where the error occurred in that file.

use:

sudo nano /etc/apt/sources.list

to edit the file. Press CTRL + O and Enter to save the file. Then CTRL + X to exit the file and then run:

sudo apt-get update

here's a default list of sources to compare to:

deb http://us.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty main restricted universe multiverse

deb http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-updates main restricted universe multiverse

deb http://us.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse
deb-src http://us.archive.ubuntu.com/ubuntu/ trusty-backports main restricted universe multiverse

deb http://security.ubuntu.com/ubuntu trusty-security main restricted universe multiverse
deb-src http://security.ubuntu.com/ubuntu trusty-security main restricted universe multiverse

deb http://archive.canonical.com/ubuntu trusty partner
deb-src http://archive.canonical.com/ubuntu trusty partner

deb http://extras.ubuntu.com/ubuntu trusty main
deb-src http://extras.ubuntu.com/ubuntu trusty main

BTW, this list has all the backports and multiverse restricted universe etc enabled but those are not needed (optional). – mchid Mar 15 '15 at 0:40
