Reset update sources

[larbac]

Hi

I can see that my office PC using 16.04 doesn't do the same updates as my home PC also with 16.04.
For instance I don't get the notifications for Firefox updates...

How can I "reset" my sources list, or at least make it equal to my home PC (if possible)?

Thanks

Do you have Muon Package Manager installed on both PCs?

Hi

No, I use Discover.

Discover, as you may already have 'discovered', is not a package 'manager', and like many of us believe, is sorely lacking.

Open a konsole and install Muon Package Manager:

sudo apt-get update && sudo apt-get install muon

Once installed, launch Muon Package Manager and click on Settings > Configure Software Sources. Look at each Tab and note what is checked. Compare those settings to your other PC to see what is different.

the sources are located at ,,,,, /etc/apt/sources.list and /etc/apt/sources.list.d (a folder with added sources) all are text files and can be printed and compared to find the discrepancies.

,,,,,,,,,just to add to what @Snowhog has already stated ,,,,,,,,and I agree ,,,Discover is NOT a package manager or a good tool for source management,,,,,,,,,,,,,it was meant just to introduce NEW users to the most popular applications.

Hi Guys

Yeah, the system automatically removed Muon and installed Discovery.
I will install Muon again and check it.
Thanks

Discover is NOT a package manager or a good tool for source management

As much as i dislike the flow of how package management works in discover it infact does work just fine as a package manager. The selection of packages shown (i.e only gui ones) is because of the lack of metadata for most cli programs (iirc) .
you can change the sources also in discover. Open it and click on settings on the left side .. it opens up the source editor directly in discover. (unlike muon that opens in a new seperate program)

I don't know if Discover is the culprit, but I've seen reports of flakiness with the updates notification mechanism. For me it came and went with 16.04 and now on 16.10 the notifier seems correct but when I click on it Discover often says there's no updates. I just use the command line

sudo apt update 
sudo apt full-upgrade

to sort things out. If you suspect an install has any problems I suggest running those.

On a 16.04 Lubuntu system I support just yesterday I found a screw up that the GUI was not reporting. I didn't understand it but I ran the above and apt told me what to do, and hundreds of updates were released.
