clarkwinkelmann yv7pmrlcem I don't think Composer released version 2 yet. Their website still lists 1.x as latest. This post has the instructions to install v2 snapshot https://php.watch/articles/composer-2 I'd recommend waiting until official release when the update instructions should appear at https://getcomposer.org/
Hiob yv7pmrlcemI should have said : I've bypass this one making a clean install without lost any data 😀
ooofree My problem might be a little different. After updating by following the operation instructions, but the version number is not updated. When the command is entered again, Nothing to install or update
raafirivero ooofree try running the following command in composer: composer why-not flarum/core v0.1.0-beta.13 - this will tell you which plugins/packages are blocking your update. For me it was FoF/upload and one other. I removed them using the composer remove [name of package] command and was able to upgrade Flarum.
raafirivero ooofree I also had an issue with wikimedia/less.php as you seem to be having. I tried to upgrade it to version 3.0 with Composer directly but the Flarum plugin was blocking it. What ended up working for me was removing it using composer remove. From there I was able to upgrade Flarum. After I upgraded Flarum what happened is that it re-installed wikimedia/less.php to the proper version (v3.0) that it wouldn't let me install before, haha.
robinodds ooofree you also have another extention that blocks beta13: fof/html-errors composer require fof/html-errors
datitisev ooofree That seems to be an issue with fof/links (based on the links table), not flarum/core.
