Repository fails to update with 404 Error.

You may need to boot into recovery mode to add your user to the sudo group

Code:

adduser paul sudo

Hi I'm having some difficulty booting into recovery mode, I press escape when after the BIOS loads but the machine continues on to the main login page. Do you have another suggestion?

Hold down the left Shift key.

OK so that was progress, I booted into recovery mode added the sudo group to my profile and ran apt get update as follows

paul@paul-desktop:~$ sudo apt-get update
[sudo] password for paul:
Sorry, try again.

Reading package lists... Done
paul@paul-desktop:~$

I am still faced with the original problem when I run the update manager I get:

Could not initialize the package information

An unresolvable problem occurred while initializing the package information.

Please report this bug against the 'update-manager' package and include the following error message:

'E:Opening /etc/apt/sources.list - ifstream::ifstream (13: Permission denied), E:The list of sources could not be read.'

Any suggestions welcome...

**oldos2er** · October 15th, 2012

Hmm. Maybe try the suggestion given here
I don't know what more to suggest.

**jerrrys** · October 15th, 2012

Like oldos2er said, or just rename and update:

sudo mv sources.list sources.list.old

and update

**Paul Lynch** · October 16th, 2012

Well that seems to work a treat, I removed the Sources list file and am currently updating. I guess I manually added some updates into the repo with errors. Anyhow once these updates are complete I plan on updating the system to the new LTR... fingers crossed

Appreciate all the help and effort

I have the same message basically and yes my internet is working fine and I have two other computers which are updating just fine. The big difference in my laptop is I went from Ubuntu 11.10 to Ubuntu 12.04. Would that make a difference? I was considering overwriting with a copy I have of Ubuntu 12.04. Please help. My laptop says my package hasn't been updated in 19 days now
