I am trying to upgrade Ubuntu 18.04 to 21.04 (i386 architecture) on a Dell laptop in order to be able to install proton VPN.
Output message:
There will not be any further Ubuntu releases
for this system's 'i386' architecture. Updates for
Ubuntu 18.04 LTS will continue until April 2023.
Are there any options to upgrade perhaps to another newer Linux platform that would support a GTK version that would be compatible with Proton VPN or is my only option to upgrade my hard disk?
