I want to install classic snap in order to use well-konown linux apt-get cmd in ubuntu core 20 according to the post:

https://askubuntu.com/questions/902905/install-applications-in-ubuntu-core

 

During installation I get following error:

rexroot@ctrlx-CORE:~$ sudo snap install classic --devmode --edge
error: cannot install "classic": persistent network error: Post
https://snapstore.boschrexroth.com/v2/snaps/refresh: dial tcp: lookup
snapstore.boschrexroth.com: Temporary failure in name resolution
rexroot@ctrlx-CORE:~$

 

Can you please help me how can I solve this issue? Thanks

ctrlX CORE is designed with high security requirements. Also, the overall ctrlX CORE architecture is built to be compliant to be certified as defined by IEC62433. This also implies some requirements for the apps and software running in the ctrlX Ecosystem. 

To install apt-get is also against the idea of Ubuntu Core, which is totally snap based. Ubuntu Core is built from snaps, a secure, confined, dependency-free, cross-platform Linux packaging format. Find out more here.
