Question

После установки библиотеки MailKit и вызова new SmtpClient().ConnectAsync(_settings.Server, _settings.Port, _settings.SSL); я получаю эту ошибку:

Access to the path '/var/www/.dotnet/corefx/cryptography/crls' is denied.

, кстати, мой проект находится на /СМИ/Projectname. Я попытался выполнить это: sudo chmod -R 755 /var, но я получил ошибку разрешения.

Answer 1

Я имел в виду это guide. В файле kestrel-hellomvc.service вместо User = www-data был заменен User = my-root-username, и он сработал. Надеюсь, это поможет кому-то.

Answer 2

Как Lex Li отправил создать /var/www/.dotnet/corefx/cryptography/crls каталог и дать права на группы WWW-данных (если это группа, которая работает ваш сервис)

Судо команда chgrp www- data /var/www/.dotnet/corefx/cryptography/crls
