I have a similar issue in that the app won't open at all, even if I go to the 'Open' tab in the installed apps list. I first downloaded the Android version and it opened the first time and worked fine but when I started using the PC a few days later I couldn't get to run. I visited the website and noticed there were scripts for installing a Linux distro, there wasn't one specifically for Zorin so I chose the Ubuntu version. I ran the two scripts, one to get the app the other (sudo) to install and all went well without any errors but I still can't get it to run. Do I have to do anything after running the sudo command or should it open from the icon in the Apps?
OK, I have run the install but it still won't run so I ran the 'checksum' and this is what I get in the terminal:
Reading package lists... Done
E: Could not open lock file /var/lib/apt/lists/lock - open (13: Permission denied)
E: Unable to lock directory /var/lib/apt/lists/
W: Problem unlinking the file /var/cache/apt/pkgcache.bin - RemoveCaches (13: Permission denied)
W: Problem unlinking the file /var/cache/apt/srcpkgcache.bin - RemoveCaches (13: Permission denied)
I'm beginning to wonder if I should just delete it and start over. Originally I installed the package from the package store and it seemed to install the android version, I got it to open, changed the country and it ran smoothly. Since then I haven't been able to get it to open at all to display an interface.
I have managed to get it to work by using Firefox as the browser (I wasn't a great fan of Brave anyway) and it's working fine now. Thanks for your help.
