Looks like all is ok with my server but something is wrong with curl on that Debian 12. Take a look: Code: root@h3-virt~# root@h3-virt~# curl https://www.phpmyadmin.net/home_page/version.txt curl: (16) Error in the HTTP2 framing layer root@h3-virt~# root@h3-virt~# curl --http1.1 https://www.phpmyadmin.net/home_page/version.txt 5.2.1 2023-02-08 https://files.phpmyadmin.net/phpMyAdmin/5.2.1/phpMyAdmin-5.2.1-all-languages.zip root@h3-virt~# root@h3-virt~# So consider maybe adding in that script parameter "--http1.1" for curl - then will always work. And I don't have any firewall or WAF on it yet.
Curl on Debian 12 is absolutely fine; the test I've shown you above is made on Debian 12. Also, we have more than 100 new installs on Debian 12 daily, and you are the only user with this issue. I understand that you do not like that your system is the only affected one, but in fact, it is. We will not limit the ability in curl to use new HTTP modes only because your system has some kind of filter or firewall on or in front of it that prevents modern HTTP transports.
And as I mentioned already, we will add some code to the updater to prevent it from renaming the folder if it was unable to reach the phpmyadmin website.
