### Describe your issue
Mastodon update (yunohost app upgrade mastodon) fails.
I get these errors (end of the log):
2025-11-11 09:01:35,098: WARNING - rbenv: version `3.4.5’ not installed
2025-11-11 09:01:35,601: ERROR - provision\_or\_update failed for ruby : An error occured inside the script snippet
I’m pasting the end of the log, because I’m a new forum user and can’t paste anything with a link and the earlier error log has links.

Hi,
Have you checked the installed versions?

What versions do you mean? Yunohost is up to date and I’m using the Mastodon ynh app. Could you point me to some extra instructions I’m should follow, in addition to just “yunohost app upgrade mastodon”?

I was talking about rbenv version `3.4.5’
To do this, use this command:
```auto
sudo yunohost app shell mastodon
```
Then, use the command which will allow you to view the installed versions.
```auto
rbenv install --list
```
If it is present, you can activate it with this command:
```auto
rbenv global 3.4.5
```
Otherwise, install the Ruby build for the specified version using:
```auto
rbenv install 3.4.5
```
Once installation or activation is complete (if present), you can rebuild the resources.
Use the following commands:
```auto
cd live
```
Afterwards,
```auto
RAILS_ENV=production bundle exec rails assets:precompile
```
It will probably be necessary to restart the Mastodon services:
```auto
systemctl restart mastodon-web.service mastodon-sidekiq.service
```

Thanks! rbenv is not in path apparently:
> sudo yunohost app shell mastodon
> rbenv install --list
> bash: rbenv: command not found
However I found out from the restore log that /opt/rbenv/bin/rbenv exists, and from that I get a list:
3.2.9
3.3.10
3.4.7
jruby-10.0.2.0
mruby-3.4.0
picoruby-3.0.0
truffleruby-25.0.0
truffleruby+graalvm-25.0.0
However - thanks again for your interest in helping me, but I gave up on Mastodon and moved my one man instance over to gotosocial. This thread can be closed for my part.
