Troubleshooting

error: This revision of snap "radare2" was published using classic confinement...: When installing the snap package of radare2, you need to specify the classic confinement. Append --classic on the installation command line.
How can I download the snap package for offline use?: Use the command snap download radare2. You can then run sudo snap install to install the .snap package that was just downloaded.
Do I need to use "sudo" with snap commands?: You need to prepend sudo when you run most snap commands that perform privileged actions. However, if you log in into the Snap Store using sudo snap login, then you do not need anymore to prepend sudo.
