Thanasis Mattas's questions

I recently upgraded to ubuntu 19.4. I used to ctrl+shift drag and drop files at desktop, in order to create shortcuts. At 19.4 some very useful functionalities are removed, I hope for good reason. You can still right-click/Create Link, or use the ln command.

The problem is that when a link is at desktop, I cannot double-click to open, nor right-click/open. Right-click/open with an other application works. Also, after right-click/Show In Files, which opens nautilus, you can just double-click to open.

Another thing, MS office files have the same behavior. Namely, I can double-click to open with Libre office, through nautilus, but when at desktop they only open with right-click/Open with an other application.

Any suggestions on how to double-click to open file-links at desktop?

Thank you

Edit: The problem is resolved at Ubuntu 20.04.

$ sudo pip install numpy    # or anything else

$ python -V
Python 3.7.3  
$ pip -V
pip 19.0.3 from /usr/local/lib/python3.7/site-packages/pip (python 3.7)
$ whereis pip
pip: /usr/local/bin/pip2.7 /usr/local/bin/pip3.7 /usr/local/bin/pip /usr/local/bin/pip3.6  

pip3.6 appeared after:

$ sudo su
$ update-alternatives --install /usr/bin/python python /usr/bin/python3 1

In anaconda environments, pip works fine.

Is deleting things related with python, at a safe extend - without breaking the system, and re-install stuff properly, a preferable solution? And how to do so?

I know that there are a lot of similar questions, but I've tried a lot of stuff (obviously, I messed something) and I haven't solve the problem.

Thanks!

I know that this question is asked before, but nothing seems to work. I have a double boot windows 10 - ubuntu 18.10 on the NVME and a 2nd 1 TB HDD drive (ntfs). Windows of course have permission on the HDD, but ubuntu doesn't (read-only).

I want to have read-write-execute permission as user (id=1000) on the HDD!

tried:

1. remount

   sudo mount -o remount,rw Sometimes works after 1st reboot, but after 2nd reboot, I had read-only permissions again

2. edit fstab

default entry:

/dev/disk/by-uuid/[disk-id] /path/to/mount auto nosuid,nodev,nofail,x-gvfs-show 0 0

changed to:

/dev/disk/by-uuid/[disk-id] /path/to/mount auto nosuid,rw,nodev,nofail,x-gvfs-show 0 0

,

/dev/disk/by-uuid/[disk-id] /path/to/mount auto nosuid,uid=1000,nodev,rw,nofail,x-gvfs-show

,

/dev/disk/by-uuid/[disk-id] /path/to/mount ntfs defaults

,

/dev/disk/by-uuid/[disk-id] /path/to/mount ntfs-3g defaults

,

dev/disk/by-uuid/[disk-id] /path/to/mount ntfs nosuid,uid=1000,nodev,rw,nofail,x-gvfs-show 0 0

3. chown

   sudo chown -R -v user:user /path/to/mount

error: failed to change ownership of '/path/to/mount' from user:root to user:user ,

chown -R user /path/to/mount

didn't work

As far as I understand, permissions are granted upon mount on boot time. So, the solution has to lie at fstab. But, the mount point is at /media/ (or by default at /mnt/) which are directories with only-root permissions, thus I tried to mount under /home/user/testDir, but got the error:

mount: /home/user/testDir: mount point not mounted or bad option

Any suggestions? Maybe, in how to properly edit fstab? Any help will be deeply appreciated.
