Error installing Daedalus Wallet on Linux

What exactly happened? Your first action:

chmod +x daedalus-2.1.0-mainnet-14079.bin

I.e. You told the OS that the file is daedalus-2.1.0-mainnet-14079.bin is the executable file. Next, you try to run this file for execution:

./daedalus-2.1.0-mainnet-14079.bin

Judging by the "./" at the beginning of the file name, it is not in the root of the file system, but in some directory of your own. The program starts and returns an error message:

/pk5wvyzbzds9wfz33q9fr5bhlf1kqcjb-startup: not found

I.e. your program daedalus-2.1.0-mainnet-14079.bin asked the OS to run another program - pk5wvyzbzds9wfz33q9fr5bhlf1kqcjb-startup but the operating system did not find this program.

There are two significant points here:

1. Name pk5wvyzbzds9wfz33q9fr5bhlf1kqcjb-startup explicitly generated. Most likely, this name was "invented" by the program daedalus-2.1.0-mainnet-14079.bin during the installation process and tried to create this file. But I couldn't create it...
2. Why didn't it work ? Most likely because in the beginning this name should be " / " - i.e. this file should have been created in the root of the file system. I suspect that your program has daedalus-2.1.0-mainnet-14079.bin did not have the rights to do this.

Well, the root cause is most likely in the settings of the paths for installing the program. Read the instructions carefully and check the paths.
