Ubuntu – How to block incoming calls from a particular phone number on an Ubuntu phone

This is not possible at the moment, but the feature has been requested:

• for calls
• for messages

You can vote for the bugs, if you want.

I followed this post on Ubuntu Forums. This solved the problem and I can see my device (Meizu MX4 Ubuntu Edition) in the file manager and transfer files without any problems.

1. Install some of the common MTP apps that will be needed. Open up a terminal and type the following two lines one after the other.

   sudo apt-get install libmtp-common mtp-tools libmtp-dev libmtp-runtime libmtp9  
   sudo apt-get dist-upgrade  
   

2. Amend the fuse.conf file. FUSE is an application that aims to provide a secure method for non privileged users to create and mount their own file system implementations. This option overrides the security measure restricting file access to the user mounting the file system. So all users (including root) can access the files. This option is by default only allowed to root, but this restriction can be removed with a change to the aforementioned fuse.conf file as follows:

   sudo nano /etc/fuse.conf
   

   We want to remove the # from the below line of code for user_allow_other, like this:

   #/etc/fuse.conf - Configuration file for Filesystem in Userspace (FUSE)
   
   #Set the maximum number of FUSE mounts allowed to non-root users.
   #The default is 1000.
   #mount_max = 1000
   
   # Allow non-root users to specify the allow_other or allow_root mount options.
   user_allow_other
   

   Now save the file by pressing Ctrl+X, type Y and then pressEnter.

3. Set up some rules for our device that we plan on connecting, but before we do that we need to find out both the vendor and product id.

   Connect your device via an available USB port and from terminal run:

   lsusb
   

   This should bring up an output similar to the following:

   Bus 002 Device 003: ID 0fce:01b1 Sony Ericsson Mobile Communications AB 
   Bus 002 Device 002: ID 8087:0024 Intel Corp. Integrated Rate Matching Hub
   Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
   Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
   Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
   Bus 001 Device 006: ID 0461:4d65 Primax Electronics, Ltd 
   Bus 001 Device 005: ID 0846:9020 NetGear, Inc. WNA3100(v1) Wireless-N 300 [Broadcom BCM43231]
   

   You need to look for your device, in this instance my Sony Tablet is at the top of the list, the vendor id is 0fce and product id is 01b1.

4. Amend the mtp udev rules as follows and type:

   sudo nano /lib/udev/rules.d/69-mtp.rules
   

   Then add the below line of code:

   # Sony Xperia Z2 Tablet
   ATTR{idVendor}=="0fce", ATTR{idProduct}=="01b1", SYMLINK+="libmtp-%k", ENV{ID_MTP_DEVICE}="1", ENV{ID_MEDIA_PLAYER}="1"
   

   Remember what you're changing here is the device name next to the #, this can be whatever you want, the # comments out the code, but for clarity and reference later I would choose the name of your tablet/phone and also the vendor id and product id, they should match what was seen when you issued the lsusb command earlier.

   Once done, save the file.

5. Add a line of code to the 51 android rules file:

   sudo nano /etc/udev/rules.d/51-android.rules
   

   Then add the following line of code:

   ATTR{idVendor}=="????", ATTR{idProduct}=="????", MODE=”0666"
   

   What is highlighted in red needs to be changed to your device product id and vendor id.

6. Once that is done and the file is saved, remove any USB device currently connected and run the following command:

   sudo service udev restart
   

7. Save any other remaining work you may have open and reboot the system.

   sudo reboot
   

Once rebooted you should now be able to plug your Android device in(making sure the screen is unlocked) and VIOLA!!(or at least I hope) You will now be able to transfer data to/from your Android device via the much quicker and much more reliable MTP
