Shutting down old Sail processes (Ubuntu)

[ghost]

Why is Laravel Sail stopping a process on Ubuntu?
The commands in wsl2 work on windows:
./vendor/bin/sail up -d
./vendor/bin/sail composer require barryvdh / laravel-debugbar --dev

but on ubuntu, docker with laravel sail
./vendor/bin/sail up -d - succeeds and starts Laravel in the background, but when trying to install the package, writes:

mysite_mysql_1 docker-entrypoint.sh mysqld Exit 1
Shutting down old Sail processes ... Sail is not running.

You may Sail using the following commands: './vendor/bin/sail up' or './vendor/bin/sail up -d'
