Ubuntu 17.10下Snap安装的VLC 3无法播放其他分区视频求助

Great question—this is a common gotcha with sandboxed apps like Snap, and I’ve run into similar issues myself back on Ubuntu 17.10. Let’s break this down:

Is this a Snap issue? #

Yes, almost certainly. Here’s why:

• Snap apps run in a strict sandbox by default, which restricts their filesystem access. Unlike the pre-installed deb version of VLC 2.2.x (which had full system access), Snap’s confinement limits VLC to specific directories like your $HOME folder, /media, and /mnt (for removable media).
• If your other partition is mounted in a non-standard location (e.g., /data instead of /media/your-drive), or if the mount permissions don’t allow the Snap sandbox to read it, VLC 3 won’t be able to access those files.

Fix for Snap VLC #

You can grant VLC access to removable/mounted partitions with a simple command:

snap connect vlc:removable-media

This adds the necessary permission to let the Snap sandbox access external drives and mounted partitions. If your partition is in a non-standard path, you might also need to adjust its mount permissions in /etc/fstab to ensure your user account has read access (add uid=$(id -u),gid=$(id -g) to the mount options).

Will Flatpak VLC work? #

In most cases, yes. Flatpak also uses sandboxing, but its permission system is more flexible, especially compared to the older Snap implementation in Ubuntu 17.10:

• Flatpak’s default permissions for VLC often include access to common mount points, but if your partition is in a non-standard location, you can manually grant access:
  • Temporary access for a single session:

    flatpak run --filesystem=/path/to/your/partition org.videolan.VLC
    

  • Permanent access:

    flatpak override org.videolan.VLC --filesystem=/path/to/your/partition
    

• Flatpak’s handling of filesystem permissions was more mature in 2017 (when Ubuntu 17.10 was released) than Snap’s, so it’s less likely to hit this exact issue out of the box.
