Snap install issues upon hard kill with Ctrl + c

[Pawel Stolowski]

Hi,

The ctrl+c behavior (bug #1596077 mentioned by Kyle) on snap install was 
fixed in December and released shortly afterwards, at least in Ubuntu.
The current version of snapd (2.20.1) in ubuntu should work - hitting 
ctrl+c now aborts the installation as expected:

$ sudo snap install mongo33
mongo33 2.84 MB / 93.59 MB 
[====>------------------------------------------------------------------------------------------------------------------------------------------------------------] 
3.04% 4.73 MB/s 19serror: cannot perform the following tasks:
- Download snap "mongo33" (2) from channel "stable" (net/http: request 
canceled)

Cheers,
Pawel
