I am quite new to Ubuntu, starting on 17.10 and am now on 18.04.
On my laptop I have 16.04 which updates perfectly, but on my desktop under 18.04 nothing seems to update automatically.
main error is "Failed to download repository information" "check your internet connection"
I have followed this thread How to resolve "Failed to download repository information"?
Chose "Best server" then "Main server" but still nothing really want to update.
One extra error I see is
E:Repository 'https://cli-assets.heroku.com/branches/stable/apt ./ InRelease' changed its 'Origin' value from 'Heroku, Inc.' to 'Heroku'
Under Synaptic though I have managed to update Sublime Text, and also Nvidia driver through a tutorial and console.
But I am yet very new to Ubuntu.
Can someone points the error that prevent Software and update
to update properly ?
(I have done everything mentioned in above thread : sudo apt-get clean
sudo apt-get update
sudo apt-get upgrade
it kinda works in console but with some warnings at the end)
EDIT
here is error on sudo apt-get update
E: Repository 'https://cli-assets.heroku.com/branches/stable/apt ./ InRelease' changed its 'Origin' value from 'Heroku, Inc.' to 'Heroku'
N: This must be accepted explicitly before updates for this repository can be applied. See apt-secure(8) manpage for details.
and error on sudo apt-get upgrade
E: Failed to fetch https://cli-assets.heroku.com/apt/heroku_6.16.18-1_amd64.deb 404 Not Found [IP: 52.85.219.14 443]
E: Unable to fetch some archives, maybe run apt-get update or try with --fix-missing?
EDIT 2
I have tried to install Ubuntu as advised here https://devcenter.heroku.com/articles/heroku-cli
with
sudo snap install heroku --classic
but got error
error: cannot perform the following tasks:
- Exécuter la configuration du point d'accroche du paquet Snap "heroku" s'il est présent (run hook "configure": /usr/local/bin/heroku: ligne 18 : cd: « HOME » non défini)
though curl https://cli-assets.heroku.com/install.sh | sh
seemed to work ans installed the newest version.
Yet the above errors from EDIT section still appear
