Slack cannot open files on external drive (in /mnt and /media)

fr flag

I have installed Slack (Desktop App) and I had trouble uploading and downloading files from/to certain directories for months. More specifically, it seems that Slack don't have the permission to access directories in /mnt and /media (and various other directories outside of /home).

I don't upload files from USB sticks everyday, however I have a dual boot ubuntu+windows and my ~/Downloads is a symlink to /mnt/win10/.../Downloads, and downloading files or sending files I downloaded previously is really fastidious.

I tried to change the umask of the mounted ntfs partition from dmask=027,fmask=137 to dmask=000,fmask=111 in /etc/fstab, to no avail. Slack cannot see the content of /mnt itself anyway (despite that permissions are rwxr-xr-x).

This github issue seemed to be the most enlightening post I could find, however I installed Slack using snap, not flatpak (and I have no problem sending files in ~/ or even /lib).

I too had faced the same issue. This is because the app did not have permission to read/write files on removable storage devices. To resolve this:

  1. Go to ubuntu setting.
  2. Go to Application.
  3. Search for Slack. Click on Slack. It will list all permission and access options for Slack.
  4. Enable read/write files on removable storage devices option.

Once enabled, you will be able to browse removable storage and upload/download files from the removable storage.

Thanks! I found the options in snap (Ubuntu Software). Worked like a charm!

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
