I using Ubuntu 20.10. All of a sudden, VLC cannot be started. When trying to run it through the command line, I get:
$ vlc
VLC media player 3.0.12.1 Vetinari (revision 3.0.12.1-0-g170157402b)
[00005573fa81cb40] main libvlc: Running vlc with the default interface. Use 'cvlc' to use vlc without interface.

VLC works well with the apt package, contrary to the snap package.

This works for me:
sudo rm /var/cache/fontconfig/*
rm ~/.cache/fontconfig/*
fc-cache -r

I had the same problem with another program. For me it was due to a restriction by the router: Ubuntu was connected to a FritzBox as guest and the FritzBox seems that was blocking this connection.
As soon as I changed to a normal connection, the problem was solved!

Qt: Session management error: Could not open network socket
Environment
You may this error when compiling a design in the Quartus® II software or running the MegaWizard™ Plug-In Manager while using VNC. The message indicates that the session manager for VNC was trying to save the state of the Quartus® II software in the event that the user logs out while the Quartus II software is still running. This behavior is not supported by the Quartus II software, and the error message can safely be ignored.
You can disable the message from appearing by running the command
unset SESSION_MANAGER
Note that this command will completely disable the session manager from running.

| emerge -f does need a network connection. -f fetches the file only. If you did a -f first, then a normal emerge, then no, you won’t need a network connection AFTER the emerge -f….. |

| So what you’re saying is that emerge -f kde worked fine, downloaded everything… But emerge kde gives you those errors? Is this correct? |

| Are you on a home network? I’ve noticed that Outlook Express seems to hog the network connection when checking for mail. _________________ http://www.catb.org/~esr/faqs/smart-questions.html#before |

| Same errors coming up as well while in the middle of building pieces of KDE. Hmm. I’m using KDM and I’ve never seen these errors before. |

| Is everyone here using userpriv in their FEATURES of make.conf? I get the feeling it’s somehow related. |

| It’s a harmless error that’s caused by running all your portage stuff as the portage user instead of as root. |
