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.
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 https://community.ubuntu.com/t/finding-help/709
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 https://help.ubuntu.com/community/EOLUpgrades
I know you’ve found support sites, as I’ve seen this request elsewhere too
