Mintupgrade to 21 requires for downgrading packages that 20.3 automatically set up to higher versions

[nicolasmol]

Hi everyone It's somewhere though to understand if upgrading to 21 has been or not officially announced, but in any case if this can help developers, let me share my experience which leads me to give up for now the updgrade.

Mintupgrade requires the following packages to be downgraded:

but fails doing it by itself for anyone of them pretended as "broken" in this list

I began to try some investigation work to identify the guilty ones doing to downgrades manually. Since any of the command lines sudo apt --fix-missing update nor the GUI tool is able to find some broken package, I tried yesterday evening the two first "libargon2-1" and "libgd3" then I gave up continuing this task for a good rest.

And guess what I see this morning? That the mint 20.3 update tool has detected the need to upgrade back again these two previously downgraded packages which demonstrates that their installation was not due to an intentional action on myself.

So what to conclude about this mintupgrade tool ? Is it ready or too soon and buggy and we should be waiting for a next release ?

[mtwebster]

What are the contents of /etc/apt/sources.list.d/official-package-repositories.list in this situation?

You are using mintupgrade 2022.08.05?

What is the output of apt policy php-bz2?

Do you have any php-related PPAs set up?

So it appears that the check pass the tests if we follow this guide before running mintupgrade : https://techviewleo.com/upgrade-to-linux-mint-21-from-linux-mint-20/ But since I'm not convinced, I didn't want to go through with the installation.

Is not suppose this mintupgrade doing by itself this ?

@holmesrichards have you tried the solution I found and suggested in my last answer ? Personally, I didn't dare for fear of making a mistake, without a prior response from the developers. Besides, I forgot to tell them this: this problem is all the more strange since my 20.3 is freshly installed not more than since the beginning of July

[mtwebster]

@nicolasmol It looks like your issue is due to the following:

The versionless php packages - php-bz2, php-curl... - are really their versioned counterparts - php8.1-bz2, etc... The versionless ones exist to make it easy to install the latest version of those packages.

The downgrading is stuck because there's no 'downgrade' to php-bz2 - it only exists as 8.1 on that PPA. Manually installing the downgraded full versions of those packages should help out apt enough to continue - if you manually install php7.4-bz2 and so on.

This issue is a shortcoming of apt and pitfall of having those generic package names.

[ghost]

There are two things here, the fact that apt can't downgrade some packages (which is not an issue) and the way the Upgrade Tool handles, or fails to handle, such errors (which is). There's nothing in the GUI to indicate the problem, it just sends you back over and over to the same dialog with no explanation. From the terminal output, if you think to look at it, you can see the apt problem, but no hint is given there or in the GUI as to how the user can proceed.

[nicolasmol]

@mtwebster Personally, my question is more this one: would be the final upgrade done and stable if before running mintupgrade I do this, since apparently when doing it, mintupgrade is able to go without prompting any error until the ultimate step "download & install"

sudo sed -i 's/focal/jammy/' /etc/apt/sources.list
sudo sed -i 's/focal/jammy/' /etc/apt/sources.list.d/official-package-repositories.list

in addition you seem to point php as being the problem, but what's about those I did not even know their role and I don't remember to be responsible for their installation...as I said previously I took example only the 2 first libargon2-1, libdgd3...etc...maybe more.
