(Solved) Signal Messenger

[felemur]

I added Signal from the Software Manager - it's a flatpak. It installed fine.

When I click on it to open, nothing happens. Read up some documentation on Signal, and there was the suggestion to confirm I have APT. I checked, and do.

I read a suggestion on the Ubuntu forum to "unset /tmp as noexec". So, I tried this

Code: Select all

david@david-OptiPlex-7010 ~ $ sudo mount -o remount,noexec /tmp
[sudo] password for david: 
mount: /tmp not mounted or bad option

       In some cases useful info is found in syslog - try
       dmesg | tail or so.
david@david-OptiPlex-7010 ~ $ 

I'm stumped.

What's the output of:

Code: Select all

$ flatpak list

OK, so to update.

I ended up using the software manager to remove Signal since it didn't launch, and tried using the code from Signal's home page to install via the terminal. It too did not work.

As a person who came from Windows, I decided to try the Restart method when something doesn't work. Normally, this computer is never restarted unless there is a kernel update - it runs 24/7.

After restarting, I tried again to install Signal from the software manager and it installed and worked upon launch.

Absolutely no idea what happened. Too busy to care at this point, I'm just happy it now does work. I always thought restarting was not the same in Linux as Windows, but shows how little I really know.

To answer your question orschiro (thank you for trying to help), here is the output:

Code: Select all

david@david-OptiPlex-7010 ~ $ flatpak list
