Is there any way to upgrade an older installation to the latest version? I have a working Mint 15 install. Instead of starting it all over from scratch, it would be nice if I could tell it to upgrade itself. I went into the Update Manager and updated everything, but it still says it is running Mint 15.
You can...but it's not recommended. Especially if you have a bunch of PPAs added to your repositories. Many of those are version specific so you'd need to remove and install the correct ones for the version of Ubu underneath Mint.
And even though Ubuntu has a do-release-upgrade command, you'll need to manually update your software sources list first for it to work.
I've done upgrades that way (in the past) and I learned they made for far more work than they saved. About the only time I've found Debian's apt-get dist-upgrade or Ubuntu's do-release-upgrade really useful was for upgrading servers. Desktops just have too much "other stuff" loaded for either upgrade command to work reliably.
Recommendation: Don't. Just do a clean install. You'll save more time in the long run.
Does anyone know if this has changed now that Mint has changed its upgrade path? That is, if I install some version of Mint 17, should I then be able to update to Mint 17.x without having to do a clean install?
Yes. You can.
I made an error in my original reply (since corrected) because I got sloppy about the difference between a release upgrade
and a version or 'dist' upgrade
. (It's a common error for which I apologise.
) Within the same major version
, apt-get dist-upgrade
is fine and probably a good idea to run since dist-upgrade
will also attempt to intelligently upgrade any dependencies
along with the installed packages plus
resolve any dependency conflicts that may result. The regular update only updates the installed packages themselves. It will not update, add, or remove anything else - including any new dependencies or unneeded packages. Additionally, any update that would change the status of another installed package won't
get downloaded or installed using just apt-get update
To clarify - a "dist
upgrade" is not
the same thing as a "release
upgrade." "dist-upgrade" works within
the same release since it uses the same repositories as a regular update.
