I'm affected too. I'm on Linux Mint 19.3 MATE (amd64) which is based on Ubuntu 18.04. Connecting to a Windows 10 machine and Windows Server 2019 fails. Connecting to a Ubuntu 18.04 server works, however.

I'm not aware of packages related to this issue being updated on the client machine (Linux Mint 19.3). I know that there has been updates on the Windows 10 machine. It could be related to a Windows update (speculative). I worked around it by adding cosmic to sources.list.d (main and universe) and apt-pinning the 4 packages freerdp2-x11, libfreerdp- client2-2, libfreerdp2-2, libwinpr2-2 to the version 2.0.0~git20180411.1.7a7b1802+dfsg1-2. I chose this version because in newer versions the libfreerdp... packages depend on libc6 >= 2.28 which would have had a too big impact (currently installed version of libc6 is 2.27-3ubuntu1). The output of the working version ist: $ xfreerdp /v:localhost /port:[localport] /u:[username] /network:modem /kbd:german /f [23:02:50:703] [21097:21098] [INFO][com.freerdp.client.common.cmdline] - loading channelEx cliprdr Password: [23:02:54:854] [21097:21098] [INFO][com.freerdp.gdi] - Local framebuffer format PIXEL_FORMAT_BGRX32 [23:02:54:854] [21097:21098] [INFO][com.freerdp.gdi] - Remote framebuffer format PIXEL_FORMAT_RGB16 [23:02:54:999] [21097:21098] [INFO][com.winpr.clipboard] - initialized POSIX local file subsystem [23:02:55:474] [21097:21098] [INFO][com.freerdp.client.x11] - Logon Error Info SESSION_ID [LOGON_MSG_SESSION_CONTINUE] -- 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/1847075 Title: xfreerdp fails with Windows 10 terminal server Status in freerdp2 package in Ubuntu: Confirmed Bug description: This happens when I try to connect to a Windows 10 server: Password: [13:29:30:958] [16417:16418] [ERROR][com.freerdp.core.nla] - SPNEGO failed with NTSTATUS: 0xC00000BB [13:29:30:958] [16417:16418] [ERROR][com.freerdp.core] - freerdp_set_last_error Unknown error class [0xC00000BB] [13:29:30:958] [16417:16418] [ERROR][com.freerdp.core.rdp] - rdp_recv_callback: CONNECTION_STATE_NLA - nla_recv_pdu() fail [13:29:30:958] [16417:16418] [ERROR][com.freerdp.core.transport] - transport_check_fds: transport->ReceiveCallback() - -1 [13:29:30:958] [16417:16418] [ERROR][com.freerdp.client.x11] - Freerdp connect error exit status 1 For comparison, the same command is working fine on RHEL7 with freerdp-2.0.0-1.rc4.el7.x86_64: [13:32:03:765] [17075:17104] [INFO][com.freerdp.client.common.cmdline] - loading channelEx cliprdr Password: [13:32:07:455] [17075:17104] [INFO][com.freerdp.gdi] - Local framebuffer format PIXEL_FORMAT_BGRX32 [13:32:07:455] [17075:17104] [INFO][com.freerdp.gdi] - Remote framebuffer format PIXEL_FORMAT_RGB16 [13:32:07:509] [17075:17104] [INFO][com.winpr.clipboard] - initialized POSIX local file subsystem ProblemType: Bug DistroRelease: Ubuntu 18.04 Package: freerdp2-x11 2.0.0~git20170725.1.1648deb+dfsg1-7ubuntu0.1 ProcVersionSignature: Ubuntu 4.15.0-65.74-generic 4.15.18 Uname: Linux 4.15.0-65-generic x86_64 NonfreeKernelModules: openafs ApportVersion: 2.20.9-0ubuntu7.7 Architecture: amd64 CurrentDesktop: ubuntu:GNOME Date: Mon Oct 7 13:31:05 2019 SourcePackage: freerdp2 UpgradeStatus: No upgrade log present (probably fresh install) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/freerdp2/+bug/1847075/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
