Update Beta 3.5.7 FAILED (Ubuntu)

[roniold]

Hi,

I’ve selected in Teamspeak Settings “Update Channel - Beta”, but when I try to update Teamspeak from 3.5.6 to 3.5.7 (Beta), I get an error like in this photo:

My Teamspeak is installed from the Flatpak and my folder with name “flatpak” has all permissions for the user ‘hijacked’, me.
Look at the photo:

AND
.
.
The file “update”

has acces too

Can you tell me with this problem? I’m new on Linux and I don’t know what I’m doing wrong.

Thank you!

the error message says you do not have write permission.
so something must be set incorrectly.
check the permissions again.

I forgot to put all permissions for the folder “flatpak”.

Now it’s working:

Thanks, have a good day!
