Ubuntu 16.04下Skype 8.14.0.10音视频通话故障求助

Let’s work through this issue step by step—since your Windows machine works perfectly on the same network, the problem is almost certainly tied to your Ubuntu 16.04 + Skype 8.14.0.10 setup. Here are actionable fixes to try:

1. Reset Skype’s Configuration & Network Data #

Corrupted local settings often cause strange connection glitches. Let’s wipe Skype’s stored preferences and start fresh:

• Close Skype entirely (check the system tray to make sure it’s not running in the background).
• Run this terminal command to delete the config directory:

  rm -rf ~/.config/Skype/
  

• Launch Skype again, sign back into your account, and test an audio/video call.

2. Verify Audio/Video Device Permissions #

Even with a solid network, Skype might be blocked from accessing your camera or microphone—this can sometimes show up as a "weak connection" error:

• Check if your user has access to the video device:

  ls -l /dev/video*
  

  Your username should appear in the group column (typically video). If not, add yourself with:

  sudo usermod -aG video $USER
  

• Repeat for audio devices:

  ls -l /dev/snd/
  

  Add yourself to the audio group if missing:

  sudo usermod -aG audio $USER
  

• Log out and back in to apply the group changes, then test Skype again.

3. Update System Dependencies #

Ubuntu 16.04 is an older release, and outdated or missing libraries can break Skype’s network stack. Let’s bring your system up to date:

• Run these commands to update package lists and upgrade existing software:

  sudo apt update && sudo apt upgrade -y
  

• Check for broken packages and fix any issues:

  sudo apt check
  

• Restart your system, then launch Skype and test a call.

4. Try a Compatible Older Skype Version #

Skype 8.14.0.10 might have compatibility quirks with Ubuntu 16.04. Let’s install a slightly older, more stable release:

• Uninstall your current Skype:

  sudo apt remove --purge skypeforlinux
  

• Download an older compatible version (e.g., 8.13.0.4) from the official Skype archives, then install it with:

  sudo dpkg -i skypeforlinux_8.13.0.4_amd64.deb
  

• If you hit dependency errors, run this to resolve them:

  sudo apt install -f
  

• Launch the older version and test your audio/video call.

5. Adjust DNS Settings #

Misconfigured DNS can make Skype misjudge your connection strength. Let’s switch to Google’s public DNS:

• Edit the DNS configuration file:

  sudo nano /etc/resolv.conf
  

• Replace existing lines with:

  nameserver 8.8.8.8
  nameserver 8.8.4.4
  

• Save and exit (press Ctrl+O, then Ctrl+X), then restart your network manager:

  sudo systemctl restart network-manager
  

• Test Skype again.
