Hi there,

What you could try doing is to remove the repository that is causing the problem and then once you are ready, you could re-add the correct repository again for the new Ubuntu version.

You could do that in two ways:

  • Find the file containing the repo definition:
grep -r mod-pagespeed /etc/apt/*
  • Open the file with your favourite text editor and comment out the mod-pagespeed lines by adding a # in the beginning of the line

  • Alternatively, you can use the add-apt-repository, the command should look something like this:

sudo add-apt-repository "deb [arch=amd64] http://dl.google.com/linux/mod-pagespeed/deb stable main"

Then update the package index: sudo apt update.

And finally, rerun the upgrade. After the upgrade is complete, you could re-add the repo as normal.

Make sure to always back up your Droplet when doing such major upgrades.

Let me know how it goes!

Best,

Bobby
