I did actually both - downloading with curl and firefox from a different machine (my workstation) and transferring it, but also downloading with curl on the 'problem' machine - wanted to narrow down the situation ...
So I did some further investigations: First I removed the already (manually) installed "hello-world" first: ubuntu@s1lp12:~$ sudo snap remove hello-world Done ubuntu@s1lp12:~$ Then installed with debug on and it worked surprisingly: ubuntu@s1lp12:~$ sudo snap install hello-world Name Version Rev Developer Notes hello-world 6.3 27 canonical - ubuntu@s1lp12:~$ Maybe the hello-world snap was cached locally or so. Hence to exclude this case I installed another package "ab". Okay, typed "ap" first: ubuntu@s1lp12:~$ sudo snap install ap error: cannot perform the following tasks: - Download snap "ap" from channel "stable" (snap not found) ubuntu@s1lp12:~$ Then did a snap find: ubuntu@s1lp12:~$ sudo snap find snap Name Version Developer Notes Summary ab 1.0 snappy-test - Test snap with shortest name audovia 3.2.2 songbuilder - Database application for making music using JFugue MusicStrings canonical-dragon 0.7.1 canonical - The gadget snap for the dragonboard canonical-i386 3.2.i386 canonical - The gadget snap for generic i386 systems canonical-pc 3.2 canonical - AMD64 generic package demo-amd64 1.2 woodrow - AMD64 generic package hello-jfh 2.10 jfh - GNU Hello, the "hello world" snap for s390x hello-world 6.3 canonical - The 'hello-world' of snaps http 4.66920160910 chipaca - HTTPie in a snap pc 16.04-0.2 canonical - AMD64 generic package roseapple-pi 1.1 woodrow - Roseapple-pi support package snappy-debug 0.23 canonical - Debug tools for ubuntu-core test-snapd-tools 1.0 canonical - Tools for testing the snapd application u1test20160920 0.1 u1test201607192 - Summary of the most simple snap ubuntu-core 16.04+20160531.11-55 canonical - The ubuntu-core OS snap xkcd-webserver 16.04-6 canonical - Show random XKCD compic via a build-in webserver ubuntu@s1lp12:~$ And was also able to install "ab": ubuntu@s1lp12:~$ sudo snap install ab Name Version Rev Developer Notes ab 1.0 4 snappy-test - ubuntu@s1lp12:~$ ... and even more packages ... Now I disabled debug mode again (logged off and on again) and I was still able to install snaps, like for example the 'xkcd-webserver' snap ?! Hmmmmm :-/ Okay, tried again on another system (on the same metal, also s390x): So no snpas installed: ubuntu@HWE0004:~$ snap list No snaps are installed yet. Try 'snap install hello-world'. .. and cannot install any - again the timeout: ubuntu@HWE0004:~$ sudo snap install hello-world error: cannot perform the following tasks: - Download snap "ubuntu-core" (124) from channel "stable" (Get https://068ed04f23.site.internapcdn.net/download-snap/b8X2psL1ryVrPt5WEmpYiqfr5emixTd7_124.snap?t=2016-08-06T15:51:49Z&h=891521db7671d969d3283ca7fe2b28ce836ee2cd: dial tcp 77.242.195.169:443: i/o timeout) ubuntu@HWE0004:~$ ... just to be sure again: ubuntu@HWE0004:~$ sudo snap install morse-converter-py error: cannot perform the following tasks: - Download snap "ubuntu-core" (124) from channel "stable" (Get https://068ed04f23.site.internapcdn.net/download-snap/b8X2psL1ryVrPt5WEmpYiqfr5emixTd7_124.snap?t=2016-08-06T15:50:31Z&h=c04f497811966572b10f4fd6a1512417aaafd061: dial tcp 77.242.195.170:443: i/o timeout) ubuntu@HWE0004:~$ Enabled debug again on this system: ubuntu@HWE0004:~$ sudo vi /etc/environment SNAPD_DEBUG_HTTP=7 ubuntu@HWE0004:~$ sudo systemctl restart snapd.service Still nothing installed: ubuntu@HWE0004:~$ snap list No snaps are installed yet.
