Not able to install hamster-snap on Debian

[iootaa]

Hi there,

I try to install hamster-snap, and faced an issue :

# snap install hamster-snap
error: cannot perform the following tasks:
- Download snap "gtk-common-themes" (1506) from channel "stable" (unexpected EOF)
- Download snap "gnome-3-28-1804" (116) from channel "stable" (http2: server sent GOAWAY and closed the connection; LastStreamID=1, ErrCode=NO_ERROR, debug="")

Nevertheless, hamster seems to be installed

# snap list
Name          Version   Rev   Tracking  Publisher   Notes
core18        20200427  1754  stable    canonical✓  base
hamster-snap  v3.0.1    43    stable    extraymond  -

but when I tried to start for the first time :

$ snap run hamster-snap
/snap/hamster-snap/43/snap/command-chain/desktop-launch: line 20: /snap/hamster-snap/43/gnome-platform/usr/lib/x86_64-linux-gnu/libgtk-3-0/gtk-query-immodules-3.0: No such file or directory
ERROR: /snap/hamster-snap/43/gnome-platform/usr/lib/x86_64-linux-gnu/libgtk-3-0/gtk-query-immodules-3.0 exited abnormally with status 127

Other tries just return nothing and hamster is not started

It's probably not related, but I'm using Tails (tails.boum.org) so I had to redirect snap through Tor :

# snap set system proxy.http=socks5://127.0.0.1:9050
# snap set system proxy.https=socks5://127.0.0.1:9050
# iptables -I OUTPUT 3 -d 127.0.0.1/32 -o lo -p tcp -m tcp --dport 9050 --tcp-flags FIN,SYN,RST,ACK SYN -m owner --uid-owner 0 -j ACCEPT

Any hint is welcomed, thank you, cheers

Update :

# snap info hamster-snap says :

Make sure to **snap connect hamster-snap:system-observe** or do the equivalent in your
 respected software center(with snap plugin enabled) before launching the gui.

So I tried # snap connect hamster-snap:system-observe

error: cannot resolve connection, slot snap name is empty

  Hamster is time tracking for individuals. It helps you to keep track of how much time you have
  spent during the day on activities you choose to track.
  
  Tips:
  
  1. Make sure to **snap connect hamster-snap:system-observe** or do the equivalent in your
  respected software center(with snap plugin enabled) before launching the gui.
  
  2. If you have launched the older version or without the plug, make sure to kill the two
  background hamster-*-service before launching again, both services will be python processes.

I'm new to snap, but this may be an apparmor/sandboxing issue

So I tried to reinstall with snap install hamster-snap --devmode

Automatically connect eligible plugs and slots of snap "hamster-snap"

@extraymond, could you have a look?

[shaneonabike]

It's weird I had it working for a looong time, and then I had to force a reboot and all hell broke loose. After doing a reinstall of teh snap I'm getting this issue as well... Did you end up resolving this problem?

[extraymond]

That's weird, sorry I don't have a debian install right now. The log seems to state something related to apparmour, check the reference and see if that helps.
