Your output shows that you are using a local Regional server in Columbia, not the Main Server.
The Main Server supplies to the regional locations; the onus is on them to ensure that their servers are updated and running. Sadly... many mirrors are a bit lax. For this reason, we suggest users having issues with regional mirrors to stay on Main Server.
What you can do to Make Certain you are on the Main Server is elevate to root as @Forpli explains here:
Once elevated to Root, select "Other locations" in the left pane, then "computer" in the right pane.
Double click on etc then on the folder named apt and then Right Click the sources.list and select to open it in Text Editor.
You can select all - then backspace and remove All Its Content to blank it out, then paste in:
