debian 10.6 x64

chillerlan/php-qrcode[3.1.0, ..., 3.3.0] require php ^7.2 -> your php version (8.0.0-dev) does not satisfy that requirement.

tried to change composer.json to ^4.3 as seen on github repo of php-qrcode.seems like fixes the issue

phpmyadmin has some issues too.

Problem 1

• Root composer.json requires php ^7.1.3 but your php version (8.0.0-dev) does not satisfy that requirement. Problem 2
• Root composer.json requires phpmyadmin/coding-standard ^1.0 -> satisfiable by phpmyadmin/coding-standard[1.0].
• phpmyadmin/coding-standard 1.0 requires php ^7.1 -> your php version (8.0.0-dev) does not satisfy that requirement. Problem 3
• phpmyadmin/sql-parser[5.0.0, ..., 5.4.1] require php ^7.1 -> your php version (8.0.0-dev) does not satisfy that requirement.
• Root composer.json requires phpmyadmin/sql-parser ^5.0 -> satisfiable by phpmyadmin/sql-parser[5.0.0, ..., 5.4.1].

Regarding phpMyAdmin, it does seem to have an issue installing under PHP8, because the version bounds are not yet updated to 8. As a workaround, you can use php7.4 /usr/bin/composer install --no-dev until it is updated.
