Update Manager SOLVED

[enjohn]

I am having problems with downloads via Update Manager. I keep getting "An error occurred" message. I have attached images of two reports in the hope that someone will be able to tell me what may be wrong. Being a complete novice, I'm unable to understand the reports. Some help, please. Thank you

Hi enjohn,

the update system is trying to read the software sources available in order to retrieve the current package lists to find out what packages you could need as updates, but there is duplicated lines in the additional-repositories file.

show the content of that file from the /etc/apt/sources.list.d/ location, <-you can copy/paste that into the file manager to get there easily. Open that additional-repositories.list file and paste the info here. If you see a google-chrome.list file also then show that info too.

ps. instead of uploading files in a post, just paste the actual log or error messages or text into the post, it makes it just very direct and effortless on both parties.

Okay, thanks for the tip on attachments. I'm sorry, but I am feeling very thick - I cannot work out where the file manager is!

You could just open the main menu, the icon at lower left, start typing file manager.

By default there are 4 icons beside the main menu button there, and one of them is the file manager. One is Firefox, the black square is terminal. You can probably hover on the icon and it might give you some pop-up info about each.

Another way to do the same thing:
- open Software Sources (it's in the main menu under Adminstration)
- from the buttons on the left, open the Maintenance tab
- on that tab, find the button called 'Remove duplicate entries'.

[zcot]

Another way

Ha! Mmm, totally forgot about that addition.

[enjohn]

Great - thank you both. The software sources were easy to find! I've removed the duplicates! I assume that the next batch of updates should now work? Should it happen again, should I follow the same method? I only have 3 buttons next to the menu.

I would expect so.

Should it happen again, should I follow the same method?

I would. It can't hurt to try. But it will only happen again if you fumble while trying to install a piece of software that is not in the Software Manager.
That is how you got the duplicate entries. It happens a lot.

I only have 3 buttons next to the menu.

At installation you should have had four: Desktop, Files, Firefox, Terminal.
Perhaps you removed one and don't recall. Did you uninstall Firefox?

Cuz, if it's not one of those things, I'd be concerned the installation was faulty.

[enjohn]

I wasn't sure what the 4 buttons were I was looking for! I haven't uninstalled Firefox, but I did change its position on the panel.

[enjohn]

Unfortunately, I have just had the same or similar issue. Whilst attempting to download a new update, via Update Manager, I've received another error! I followed the same procedure as before. When I clicked on "Remove Duplicates" I received the message "No Duplicates Found". I am unable to update anything at the moment. Every time I receive the same error message. Any ideas, please?

delete either line 1 from /etc/apt/sources.list.d/additional-repositories.list or line 3 from etc/apt/sources.list.d/google-chrome.list

[enjohn]

delete either line 1 from /etc/apt/sources.list.d/additional-repositories.list or line 3 from etc/apt/sources.list.d/google-chrome.list

Thanks for your reply. Where do I find these lines to delete? Apologies - total novice.

[djph]

In the files named in the error ... the full path was given.

[enjohn]

I've been trying most of the day to find these files so that I can delete the lines advised. I have tried everything I could from various articles and videos. I tried in the File Manager and Terminal without success. Although I did find one of the files in Terminal, I couldn't work out how to delete the line. I would appreciate a more detailed explanation when anyone has the time. Thanks in advance. Off to bed now, with a headache.

show the content of that file from the /etc/apt/sources.list.d/ location, <-you can copy/paste that into the file manager to get there easily. Open that additional-repositories.list file and paste the info here. If you see a google-chrome.list file also then show that info too.

I'm gonna repeat the same thing as above, using a different method, a little bit more manual, and maybe obvious:
1. open the file manager

You could just open the main menu, the icon at lower left, start typing file manager.

2. Click on the left pane where it says "File System"
3. Open the folder on the right that says etc
4. open the folder that says apt
5. open the folder that says sources.list.d
6. there you are able to see the 2 interesting files that need to be addressed.

You want to show us the contents of those 2 files we've been talking about.

OR, if you can open both of them and see that there is obvious duplication in one or both files, then you can do as djph suggested and edit them yourself, one one is needed. The assumption is that both files contain exactly the same line as each other. However you are fine to post the contents of both here and one of us will give an exact suggestion. I would suggest that removing the line from the additional-repositories file would be a more appropriate edit, as opposed to removing the line from the google-chrome file, which would make that basically a useless file. But functionality-wise, the end result is the same.

If you did want to go ahead and edit them, one, or the other, you need to have elevated permission to do so. One method is by using right-click methods in the file manager and you will be able to get the opportunity to use "Open as Root" on each file, this will give you the elevated permission to do so.

Or you can copy/paste the following 2 lines, one-at-a-time, using the terminal, it will open the file nicely for you, with permission, and you can edit it with the same easy visual Xed text editor.

Code: Select all

xed admin:///etc/apt/sources.list.d/additional-repositories.list

Code: Select all

xed admin:///etc/apt/sources.list.d/google-chrome.list

Looking for the terminal application, the black square icon beside the main menu at the lower left, or just enter the main menu and start typing "term i n ...".

[enjohn]

Hey! That's exactly how I need a process like this explained. Particularly at my current Linux absolute beginner/novice level. Thank you for taking the time with your explanation. I have only just woken up, after quite a bad night. I will work through this later on this morning. Thanks again.

I wasn't sure how to actually delete which line, so I have listed all the files below.

I also tried the terminal route, again wasn't really sure what I was doing and didn't want to break it.

Having both of those files is not a problem, only that the google-chrome line should not exist in both.

The additional-repositories.list file, not to be confused with Additional-repositories.list, could be empty and this is not a problem.

For me, and because this is the way that the google-chrome source configures this setup, I would just keep the configuration in the default google-chrome.list file and delete the duplicate in the other file.

The additional-repositories.list file is not required. It can be used to specify other repository entries. Any other .list file could also be used, the system will just read any available .list file in that folder/directory and try to use it.

The quickest/easiest fix for this setup, because you are not using other entries, and the edit would just make the file empty, would be to simply delete the additional-repositories.list file.

copy/paste terminal command to remove that file, using the required elevated permission. sudo will elevate, rm is the remove command, and the specific path and filename are the target:

Code: Select all

sudo rm /etc/apt/sources.list.d/additional-repositories.list

[enjohn]

Thank you for the information. I have done as you suggested and the additional-repositories.list has been removed. Do I need to do anything else at this point? Currently, I do not have updates that need downloading. Do I wait for them to show up, or is there a way I can run some sort of test to see if it has solved my issue?
