Can't update to 4.3.8 via Composer

I Just learned the info I included in my original post reflects what's on my machine, not what's in the repo, so ignore that.

Composer why-not reports this:

drupal/search_api_solr   4.3.8   requires     solarium/solarium (^6.3.7)
drupal/recommended-project dev-master does not require solarium/solarium (but 6.3.6 is installed)

I'm on Drupal 10.4.6, if that's relevant.

Problem solved, though I'm not sure why specifying to update dependencies was necessary. This worked:

composer require 'drupal/search_api_solr:^4.3' --update-with-all-dependencies

I am also seeing this ... Search API Solr is stuck at 4.3.7 and won't update to 4.3.8.

All other modules (Search API, Leaflet, Cache Exclude, etc.) got updated fine, except for Search API Solr. This is from my composer.json:

        "drupal/search_api": "^1.29",
        "drupal/search_api_solr": "^4.2",

Like I wrote, Search API was updated fine with composer update drupal/search_api to version 1.38.0 ...

Yet, composer update drupal/search_api_solr reports back "Nothing to install, update or remove".

So there seems to be a problem with Search API Solr. We shouldn't need to give it special treatment with "--update-with-all-dependencies", right? So I'm re-opening this issue.

I don't think that this is an issue with search_api_solr, but with your installation. Run
composer why-not drupal/search_api_solr:4.3.8

Thanks for the suggestion, I get the same message as @jmcintyre:

$ composer why-not drupal/search_api_solr 4.3.8
drupal/search_api_solr     4.3.8    requires         solarium/solarium (^6.3.7)                 
drupal/recommended-project dev-main does not require solarium/solarium (but 6.3.6 is installed) 
Not finding what you were looking for? Try calling `composer require "drupal/search_api_solr:4.3.8" --dry-run` to get another view on the problem.

Here's the result of the suggested --dry-run:

$ composer require "drupal/search_api_solr:4.3.8" --dry-run

  Problem 1
    - Root composer.json requires drupal/search_api_solr 4.3.8 -> satisfiable by drupal/search_api_solr[4.3.8].
    - drupal/search_api_solr 4.3.8 requires solarium/solarium ^6.3.7 -> found solarium/solarium[6.3.7] but the package is fixed to 6.3.6 (lock file version) by a partial update and that version does not match. Make sure you list it as an argument for the update command.

Use the option --with-all-dependencies (-W) to allow upgrades, downgrades and removals for packages currently locked to specific versions.

Installation failed, reverting ./composer.json and ./composer.lock to their original content.

Composer [require drupal/search_api_solr:4.3.8 --dry-run] failed, composer command failed: exit status 2. stderr=

From composer.lock:

... and:

For whatever reason you must have installed solarium 6.3.6 explicitly.
Simply remove solarium from composer.json.

I believe I have not installed solarium/solarium explicitly, by itself, or in a specific version.

Do you mean the Drupal installation composer.json? Because it is not listed there ... Or do you mean composer.lock?

Never edit composer.lock!

Edit the top level composer.json.

I believe I have not installed solarium/solarium explicitly, by itself, or in a specific version.

You must have done that. A contrib module can't do it.

It's not present in composer.json, like I wrote:

Do you mean the Drupal installation composer.json? Because it is not listed there [...]

$ cat composer.json | grep sol
"drupal/search_api_solr": "^4.2",

@jmcintyre: Do you remember if you have installed solarium/solarium explicitly, by itself, or can you see it in the composer.json of your Drupal installation?

When I tried to update to the 4.3.10 security release for Search API Solr, I still got the "package is fixed by partial update" message, blocking the update.

I finally just deleted the composer.lock file, ran composer install, and the latest versions were installed of Search API Solr and solarium/solarium.

Odd that this happened ¯\_(ツ)_/¯ ... anyway, fingers crossed, that it won't happen next time.

Since both @jmcintyre and me have updated our versions, it's no longer relevant for us, and we can close it. It can always be revisited, should it happen again.
