Ubuntu

Error while Reloading SPM – frequently appears.

Asked by Navin Talati

Sir,

While reloading the “Synaptic Package Manager” in Ubuntu 18.04 LTS, the undermentioned error appears very frequently regarding failure of fetching the required packages to update.

---------- E R R O R --------------------------

Could not download all repository indexes

The repository may no longer be available or could not be contacted because of network problems. If available an older version of the failed index will be used. Otherwise the repository will be ignored. Check your network connection and ensure the repository address in the preferences is correct.

Failed to fetch http://p/dists/pa.launchpad.net/linuxuprising/apps/ubuntu/InRelease Could not resolve 'p'Some index files failed to download. They have been ignored, or old ones used instead.

--------------------------------------------------

There is no problem in network connection / internet connectivity.
Why this happens?
What are the commands to resolve them?

Please guide.

I assume that you have created a nonsense entry in your /etc/apt/sources.list configuration file.

Please provide the output that you receive for the commands

uname -a
lsb_release -crid
find /etc/apt -name '*.list' -exec bash -c 'echo -e "\n$1\n"; cat -n "$1"' _ '{}' \;

If you have a close look at your Output, you should see that the two last lines in /etc/apt/sources.list have a complete different look that all other lines. They are nonsense.

Suggestion:

Issue the command
sudo gedit /etc/apt/sources.list
and in the editor window that opens scroll down to the very end and delete the last two lines (those containing linuxuprising).
Then save the file and close the editor.

Means #99 and #100 are to be deleted?
Is my understanding correct?
