Change distro version check from lsb_release to os-release (#2436)

In case that no static AWS credentials are specified, we try to create the boto3 client without explicitly passing static credentials. This way, we can benedit from dynamic credentials in AWS environments (e.g. using EC2 instance roles)

 CHANGELOG
 =========
 
+Version 71 (January 4, 2025)
+----------------------------
+
+(Version 71a was posted on January 6, 2025 and fixes a setup regression.)
+
+Upgrades
+
+* Roundcube upgraded to version 1.6.9.
+* Z-Push upgraded to version 2.7.5.
+
+Automated Maintenance
+
+* Daily automated tasks are now run at 1am in the box's timezone and full backups are now restricted to running only on Saturdays and Sundays at that time.
+* Backups now exclude the owncloud-backup folder so that we're not backing up backups.
+* Old TLS certificates are now automatically deleted to improve control panel performance.
+
+Setup
+
+* Fixed broken setup if SSH was configured to listen on multiple ports.
+* Ubuntu MOTD advertisements are now disabled.
+* Fixed missing Roundcube dependency package if NextCloud isn't installed.
+
+Control Panel
+
+* Improved status checks for secondary nameservers.
+* Spamhaus is now queried for the box's IPv6 address also.
+* DSA and EC private keys are now accepted for TLS certificates.
+* Timeouts for loading slow control panel pages are reduced.
+
+And other minor fixes.
