Source: awscli Version: 2.14.6-1 Severity: serious Control: forwarded -1 https://github.com/aws/aws-cli/issues/5943 awscli is not installable in Debian Unstable because python-cryptography has been updated to a newer version than permitted in awscli's dependencies. I recommend dropping the upper limit. Alternatively you could increase the limit to a higher version. Thank you, Jeremy Bícha
