I have always used Pcloud on my laptop since Zorin 15. But after I upgrade to Zorin 16 I can't open appimage application bundle. Pcloud only has appimage application bundle to make it executable. I changed the permissions on the setting to "allow executing file as program" but doesn't work. I don't know what's wrong with my system setting, because I can't open all appimage applications.
This is odd. I can think of no reason for this... And on Zorin OS 16, I am able to launch all appimages including pcloud.
Can you try launching it from terminal. Open a terminal in the directory containing the appimage (Or cd to it). Start the appimage with ./(appimage-name)
On mine for deadbeef, for example:
./deadbeef
Note the terminal printout for errors or messages that may tell us what is going on.
I left pcloud because it states it is based in Switzerland but when I came to delete my account it stated all its servers are in the US - no doubt in Google's Mega Warehouse Store. If you value your privacy, invest in an e/OS Fairphone 3 - you get 1 Gb storage free, which is all I need, and an @e.email address - well worth it. If you want more storage, €99 euros buys you 12 months storage of 20 Gb.
I understand pCloud uses Java - also not good as I was scorned for uploading an image on the Devuan forum as accessing such would spread java over his machine!
Thank you for your recommendation, I will try the /e/ cloud. Could I open the /e/ cloud as local storage like Pcloud or Google Drive in my Zorin Laptop? or I must access the cloud via application or browser?
