Recent versions of samba, including the one released with bionic, default to a higher versions of the protocol which lacks this feature. As a result, the "other locations -> windows network" tab in Nautilus is empty even when there are windows or samba machines in the network. Accessing such machines directly, via smb://<name-or-ip>/ type urls, continues to work. The fix is two-fold: - introduce a new samba API call that can be used to set the protocol version to use - change applications to make use of this API call to set the protocol versio to SMB1/NT1 just for the network browsing gvfs was updated to make use of this api call, if detected at build time. To complete this SRU, gvfs needs a no-change rebuild *after* samba was accepted into proposed. [Test case] * Launch a bionic desktop vm. You can start with a server one, and then install the "ubuntu-desktop" package. In the same command, also install the packages we need for this test: $ sudo apt update $ sudo apt install ubuntu-desktop samba smbclient * set a password for the ubuntu user, so you can login at the graphical console $ sudo passwd ubuntu * reboot $ sudo reboot * login at the graphical console as the ubuntu user. Go through the first-user-setup motions as you want. * try to browse the windows network via "other locations -> windows network". You will get an empty folder. * update the samba and gvfs packages * logout and login again on the gui, browse the windows network again. This time it will show the "WORKGROUP" folder, and if you click through, you will see yourself (your VM). [Regression potential] The samba update itself just introduces and exposes a new API call. It's up to other applications to make use of that. gvfs was patched to detect this call at build time and use it if it's detected. Packages that are not rebuilt will not see the change, and packages that *are* rebuilt will only see the change if they make use of it. [Other Info] This update introduces a specific runtime dependency between gvfs and libsmbclient due to the new API call added to the latter. Any package that is rebuilt with libsmbclient and makes use of that API call will get this specific dependency. This is handled automatically by dh_mkshlibs. To complete this SRU, gvfs will need a no-change rebuild after samba was accepted into proposed. Nautilus should show smbtree nad host on the smb network. When inputing this command: killall gvfsd-smb-browse && GVFS_DEBUG=1 /usr/lib/gvfs/gvfsd-smb-browse You can see the error: smb-network: Queued new job 0x55b19a2c9f40 (GVfsJobCreateMonitor) smb-network: send_reply(0x55b19a2c9f40), failed=1 (Action not supported by the processing engine) smb-network: backend_dbus_handler org.gtk.vfs.Mount:QueryFilesystemInfo (pid=5708) smb-network: Queued new job 0x55b19a2e7820 (GVfsJobQueryFsInfo) smb-network: send_reply(0x55b19a2e7820), failed=0 () smb-network: backend_dbus_handler org.gtk.vfs.Mount:Enumerate (pid=5708) smb-network: Queued new job 0x55b19a2c30c0 (GVfsJobEnumerate) smb-network: send_reply(0x55b19a2c30c0), failed=0 () Proposed solution: Add gvfsbackendbrowse-switch-to-NT1.patch disscused on RedHat Bugzilla [link]https://bugzilla.redhat.com/show_bug.cgi?id=1513394 which implements "change to NT1" in gvfs-smb-browse to browse smbtree to aviod adding "max client protocol" = NT1" to smb.conf to switch all samba to unsafe NT1 which most users are doing to correct this bug.
