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
