I am running Sparky Testing Minimum GUI on an old acer netbook. Since this update this morning I cannot access to the internet any more. An update is no longer possible - no website - but the connection to the router is available (I can see the icon) - but I cannot open Fritz-Box-menu.

Haven't changed the system - it is running since month unchanged. Don't know what to do  ;/

When I try to reboot - shutdown has problems - takes a long time. 'Running jobs'

While booting I can see 1 problem (but cannot read it) - the rest works fine. Boots, browser starts - but nothing happens.

Post content of /var/log/dpkg.log and /var/log/apt/history.log . Also run sudo journalctl -b in terminal and share the result.

Do not post the stuff I asked for directly on the forum. Upload it to pastebin.com and share the links.

Ok. I've done some debugging.  If you have firewall (aka ufw) active, disable it. Run sudo ufw disable

Moved older iptables packages to Sparky testing repos so should be fine, until a new version will be available in Debian testing repos.

@Mic_a your issue ''I cannot access to the internet any more'' seems to be caused by regression in newest iptables release (v 1.8.4). As Pavroo mentioned workaround for this issue has been already applied. What you should do is to disable firewall sudo ufw disable
Next you do full system upgrade sudo apt update && sudo apt full-upgrade this will downgrade iptables to last working version [1.8.3]. Now you can enable firewall once more sudo ufw enable
