Configuration

aqtinstall can be configured through a configuration file. A default configuration is stored in aqt/settings.ini file.

You can specify custom configuration file through AQT_CONFIG environment variable or “-c” or “–config” command line option.

A file is like as follows:

Settings

The [aqt] section configures basic behavior.

concurrency:

concurrency is a setting how many download concurrently starts. It should be a integer value.

baseurl:

baseurl is a URL of Qt download site. When you have your own Qt download site repository, you can set it here. It is as same as --base option.

7zcmd:

It is a command name of 7-zip. When aqtinstall is installed without recommended library py7zr, it is used to extract archive instead of py7zr library. When --external option specified, a value is override with option’s one.

print_stacktrace_on_error:

print_stacktrace_on_error is either True or False. The True setting causes a stack trace to be printed to stderr any time an error occurs that will end the program. The False setting will hide the stack trace, unless an unhandled exception occurs.

The [requests] section controls the way that aqt makes network requests.

connection_timeout:

connection_timeout is a timeout in second for connection. It is passed to requests library.

response_timeout:

response_timeout is a timeout in second how much time waiting for response. It is passed to requests library.

max_retries:

Deprecated; please do not use this setting. It has been replaced by the

max_retries_on_connection_error:

max_retries_on_connection_error is an integer that controls how many times aqt will try to reconnect to the server in the case of a connection error.

retry_backoff:

retry_backoff is a floating point number that controls how long aqt will sleep between failed connection attempts. Setting this value too low will hammer the server, and may result in no successful connections at all.

max_retries_on_checksum_error:

This setting controls how many times aqt will attempt to download a file, in the case of a checksum error.

The [mirrors] section is a configuration for mirror handling.

blacklist:

It is a list of URL where is a problematic mirror site. Some mirror sites ignore a connection from IP addresses out of their preffered one. It will cause connection error or connection timeout. There are some known mirror sites in default. When you are happy with the default sites, you can override with your custom settings.

fallbacks:

It is a list of URL where is a good for access. When mirror site cause an error, aqt use fallbacks when possible. You can find a list of mirrors at: https://download.qt.io/static/mirrorlist/
