### Summary of the issue

How to install custom application / add-on to Nextcloud which is installed via Ubuntu snap?

### Steps to replicate it

1. This is the app for Deck which I want to try - [GitHub - rallisf1/nextcloud-deck-time-tracking: A complementary app for Nextcloud Deck](https://github.com/rallisf1/nextcloud-deck-time-tracking)

2. As I understand I need to drop those files to under Nextcloud htdocs/apps folder - OK sounds easy !

3. But of course the /snap/nextcloud/50464/htdocs/apps/ is read-only as it is mounted via Snap

4. There is also /var/snap/nextcloud/current/nextcloud/ which is write-able - I tried saving it there

5. But what is next - should this now appear in NextCloud Admin UI at [https://nextcloud.my](https://nextcloud.my)./index.php/settings/apps/disabled ? It does not

6. I tried searching but cannot find anything that fits here - of course there are lots of snap specific sources

Sorry upfront guys, this must be a very noob question and the answer has to be very simple! please nudge me to the right direction, what / where / why ? 🙂

Hey @realaaa welcome back 👋

yeah… that’s not simple when you’re using the snap. Adding apps that way will break automatic upgrade capabilities.

its not a noob question… and there are no descriptions either, see reason above.

thank you very much for quick reply 🤝

I thought I was going crazy for a minute, not being able to figure this out..

I found this crazy how-to - [https://www.reddit.com/r/linux/comments/10i6m19/i\_figured\_out\_how\_to\_modify\_installed\_snaps/](https://www.reddit.com/r/linux/comments/10i6m19/i_figured_out_how_to_modify_installed_snaps/) - but definitely was not something that felt right or even sane thing to do

it makes sense I guess yes, snap is all in one and therefore you compromise on flexibility and tweaking it - lesson learned !
