Can't update old ubuntu version


I have a very old laptop Toshiba Satellite M305-S4848, from 2010. I used to run Ubuntu 14.04 on it until a few years ago. Now, I’m trying to use it again. Everything is fine, except for the fact it can’t update its Ubuntu 14.04 (nor the Firefox). It tells me to check the internet connection, but everything else is fine. I’m even typing this from it right now.

Please, how should I proceed to solve this?

Thanks in advance.

This looks like a technical support request.

This site is for the co-ordination of the Ubuntu project(s), and other non-support matters. For Ubuntu Support options, please have a look at

Ubuntu 14.04 LTS is EOL (end-of-life) thus isn’t supported on some support sites, and Ubuntu 14.04 ESM is in extended support and is supported by Canonical via Ubuntu Advantage. Refer

I know you’ve found support sites, as I’ve seen this request elsewhere too

@jairoamaral Are you sure you are connected to the Internet? If so, you can try the following:

Switching to

You can replace and with in /etc/apt/sources.list.

sed command:

sudo sed -i -re 's/([a-z]{2}\.)?|' /etc/apt/sources.list

Updating to the latest version

You can they try updating to the latest version using:

sudo apt-get update && sudo apt-get dist-upgrade
sudo apt-get install ubuntu-release-upgrader-core
sudo do-release-upgrade

This should fix the issue.

Don’t do this. @jairoamaral said they’re on 14.04 LTS which is still a supported release and has not moved to old-releases.

@popey Hmm, I thought Trusty had been moved to Just checked and looks like that’s not the case.

@jairoamaral As @popey pointed out, please don’t do it. Could you tell me the commands you ran to upgrade Ubuntu?


  • @guiverc clearly explained the issue and your options.
  • This is a fairly common support query, and belongs in a support venue.
