Rocket.chat: Updating snap not possible if rocket.chat was stopped and restarted

[d-sko]

Your Rocket.Chat version: snap rocketchat-server 0.43.0 rev. 88

Updating the snap with snap refresh rocketchat-server is not working after stopping and starting rocket.chat with snap [disable/enable] rocketchat-server:

# snap refresh rocketchat-server
error: cannot refresh "rocketchat-server": cannot refresh local snap "rocketchat-server"

Steps to reproduce:

1. install rocket.chat snap install rocketchat-server
2. stop rocket.chat snap disable rocketchat-server
3. start rocket.chat snap enable rocketchat-server
   
   
   
   • note that from this point on snap list does not show a developer for rocket.chat
   
   
4. try to update rocket.chat snap refresh rocketchat-server
5. you'll see the error mentioned above

Even a restart of the whole server does not fix the problem. Someone also posted this on the Ubuntu bug tracker.

@d-sko thanks for reporting. This is definitely an issue with snapd. I'll see if I can bump this that ticket and see where things are at.

Just an update on this, looks like they will have a fix for it released in 2.17.1.

Trying to find out what we can do to get you guys unstuck and upgraded.

@Har01d / @d-sko to fix this you are going to need to back up your data and install the snap again.

[edit 12/18/2017] Don't use this.... Use official docs: https://rocket.chat/docs/installation/manual-installation/ubuntu/snaps/#how-do-i-backup-my-snap-data

cp -R /var/snap/rocketchat-server/common ~/rc-backup
sudo snap remove rocketchat-server

# if you want to make sure no data is left over (i don't think there will be) you can do:
# sudo rm -rf /var/snap/rocketchat-server

sudo snap install rocketchat-server

sudo systemctl stop snap.rocketchat-server.rocketchat-mongo
sudo systemctl stop snap.rocketchat-server.rocketchat-server

sudo cp -R ~/rc-backup/* /var/snap/rocketchat-server/common

sudo systemctl start snap.rocketchat-server.rocketchat-mongo
sudo systemctl start snap.rocketchat-server.rocketchat-server

@geekgonecrazy, thanks, that helped!

The problem is in snapd itself, it will be fixed in the 2.17.1 release

[geekgonecrazy]

@Har01d correct. This is the communication I got from the snap team as well.

[geekgonecrazy]

Going to go ahead and close this as 2.18 has also already been released. Please follow above instructions if you need to get yours unstuck

Still the same problem

$ snap list
Name Version Rev Developer Notes
core 16-2 1512 canonical -
rocketchat-server 0.46.0 204 -

$ snap --version
snap 2.23.5
snapd 2.23.5
series 16

The reinstall fix above hasn't worked. Probably doesn't like the jump from 0.46 to 0.53
After install rocket chat will load then after copying backup to common it will fail.

Is there an _easy_ fix yet? According to @GenericUK reinstall won't do it.
We've got a Rocket.Chat installation here, that just stopped to work. I guess and automatic update happened there...
