[Solved] Having trouble with update manager.

[Confused_nerd]

Hello, I'm using linux mint 20.1 (ulyssa) version.
A few days ago, I was checking for updates using the GUI update manager.
I clicked refresh button on the top toolbar, then it opened up a window like it always does.
While it was doing its thing, the wi-fi went down midway, then the window showed an error message( understandable ).


But when the wi-fi came back up again and I tried to refresh again, it started showing an error message.
It's been showing that same message everytime I try to update. Here's the message:

The windows heading says: synaptic

Below that says: 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.

The text in the middle of screen says:

Skipping acquire of configured file 'main/binary-armhf/Packages' as repository 'http://packages.linuxmint.com ulyssa InRelease' doesn't support architecture 
'armhf'Skipping acquire of configured file 'upstream/binary-armhf/Packages' as repository 'http://packages.linuxmint.com ulyssa InRelease' doesn't support architecture

After that the error window just closes, and the manager home is shown saying "Your system is up to date."
Please help. Thanks.

Open Update manager....click on EDIT....then Software Sources.
you should see::

left click on the Main(ulyssa) line....just onces...it will start showing you the speeds of the various mirrors....select the one with the fastest speed.
Do the same for the Base(focal line)....

It will throw open a message at the bottom of that window telling you 'Ypour Configuration has Changed...click OK to update your APT cache.
Do that.....and then click on refresh on the main Update window, and all should be well again.

I wonder why it shows:

binary-armhf/Packages

and:

http://packages.linuxmint.com ulyssa InRelease' doesn't support architecture

?
Is this installed on an ARM cpu based machine?
Does Linux Mint offer a version for ARM?

 

[captain-sensible]

thats what i was thinking Archetecture as in armhf==arm, Mac,Windows, Linux 32 , linux 64 , Unix BSD

Hi, I tried doing that but everytime it's showing this error message:

What should I do now?

I think my system is amd64 (I got no idea what that means, just that my machine installs .deb packages that have amd64 in them and not others).

Did you do this ?
It will throw open a message at the bottom of that window telling you 'Ypour Configuration has Changed...click OK to update your APT cache.
Do that.....and then click on refresh on the main Update window, and all should be well again.

Can you try this command for me:

sudo dpkg --remove-architecture armhf

Then, in the terminal, run the following:

sudo apt update && sudo apt upgrade -y
