@Pascal > the Ubuntu Desktop Team is too lazy to provide one
Those statements are not welcome here, see the code of conduct - http://www.ubuntu.com/project/about-ubuntu/conduct. Bug reports are handled by humans, the majority of whom are volunteers, so please bear this in mind. As I've explained to you on IRC yesterday, new versions/series carry risk of regression. The Ubuntu policy has high requirements for stable updates because we believe that breaking a working system has a more severe impact than having something which hadn't been working from day 0 not resolved (nobody is relying on it and it's not going to stop production since it never worked). You might disagree with the policy but please let's not get into personal opinions. There are other distributions for those who prefer updates in risk of getting regressions. It's also possible to use non LTS Ubuntu series. Going back to the issue, it's not a question of being lazy but just to set priorities. The bug has been reported once, it is an issue but in a non common configuration. It would be nice to have that one and others fixed but we have a small teams and lot of components to maintain. We might eventually get to it but probably not at this point unless we see an higher number of users impacted. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to freerdp2 in Ubuntu. https://bugs.launchpad.net/bugs/1999595 Title: Cannot connect via IPv6: "invalid cbClientAddress value: 82" Status in freerdp2 package in Ubuntu: Confirmed Bug description: I am trying to access a remote computer that does not have a publicly- routable IPv4 address. Let's say that MyHostName.MyDomain.com has an IP address of 2001:db8::1. If you look it up in DNS, you get no A records and one AAAA record. Using both Remmina and gnome-connections, I am unable to connect to the RDP servers MyHostName.MyDomain.com, 2001:db8::1, nor [2001:db8::1]:3389. Tonight, I'm on the same LAN as this server; I tried connecting to its LAN IPv4 address, and that worked perfectly. I used `nmap` and confirmed that TCP 3389 is open over IPv4 and IPv6 (the latter available over the WAN, too), and `ss` confirms that `gnome-remote-desktop` is listening for IPv4 and IPv6 connections. ## Server logs ``` Dec 13 21:37:18 MyHostName gnome-remote-desktop-daemon[10519]: [21:37:18:358] [10519:12845] [WARN][com.winpr.negotiate] -
