Hi,

Trying to upgrade to Trisquel 8. I used the 'Software Updater' under 'System Settings' which tells me that "The software on this computer is up to date. However, Trisquel 8.0 LTS is now available (you have 7.0)." So I click 'Upgrade...' and authenticate, click 'Upgrade' again on the Release Notes. Then there's some messages about rewriting 'sources.list' ("No valid mirror found" and "Generate default sources?") but I don't care about that so I just click yes. Then I get stuck! The error message is as follows:

"Error authenticating some packages. Continue?

It was not possible to authenticate some packages. This may be a transient network problem. You may want to try again later. See below for a list of unauthenticated packages.

linux-image-generic"

How can I get the upgrade to work please? Also, please provide "safe" instructions as I really don't want to have to restore my system from backup (possible if necessary but not preferred) as that might be tricky if the system won't boot!

Many thanks in advance,
Steve

P.S. Trisquel 7 is great BTW! Thanks :)

Hi Steve-O,

I'm doing an upgrade today too and hit the same issue with Software Updater. The alternative to using Software Updater is to perform the upgrade from the command line. Which I'll explain below. This is no less safe, but upgrading always carries some risk, so if this system is important to you, you *must* be prepared in case there are problems. An approach I recommend is to buy a second hard drive and get an appropriately skilled person to clone your existing system onto that drive. Then you can swap in the new drive and perform the upgrade on it, leaving the old one intact in case of problems.

First use Software Updater to ensure that your Trisquel 7.0 system is completely up-to-date.

Then open the Terminal program and update the package references to Trisquel 8.0:

sudo gedit /etc/apt/sources.list

In the editor, replace all references to "belenos" with "flidas" (try Search, Replace in the menu). Save and close the editor. Then update your packages list with:

sudo apt-get update

Then perform the upgrade with:

sudo apt-get dist-upgrade

That will busily download and install all the packages, taking quite a while. When it's completed you'll need to reboot your machine. Now you're running Trisquel 8.0!

Regards,
Ben

Excellent! Thank you so much for the tips. And that is a great idea about running the upgrade on a second hard drive. I am going to do it that way to be on the safe side. Cheers :)

For what it's worth, my upgrade experience was fairly bumpy. I ended up with quite a few packages failing to install due to conflicts, requiring manual removal with aptitude, because apt-get was stuck. Got there in the end.

Thanks. At least I'm not alone!

I just though... If the GUI upgrader is complaining about something, won't the command line upgrader run into the same problem? Because the GUI is just a front-end that will ultimately be performing the same actions as the command-line approach, right?
