**What app is this about, and its version** : synapse 1.53
**What YunoHost version are you running** : 12.1.40.1
**What type of hardware are you using** : Old laptop or computer
### Describe your issue
Upgrading synapse failed due to connection issues.
Then restoring the backup also failed.
Apparently it has something to do with the go version.
Any help appreciated. Link to complete log below.

Hello,
Seem exactly the same issue than [Failed to update 1.129 to 1.130 · Issue #549 · YunoHost-Apps/synapse\_ynh · GitHub](https://github.com/YunoHost-Apps/synapse_ynh/issues/549). Could you confirm ?

Thanks for your reply - yes it seems very much like the same error related to lk\_jwt. As one suggests on the link you provided I tried removing golang-go with apt and then apt autoremove as well, but it ends up missing go:
> Info: DEBUG - env: ‘go’: No such file or directory

And then after installing golang-go again - same situation as before, full log:

Hello,
The correct solution is to not install manually with APT golang. It’s expected to be installed as a resource. So now is seem that it’s not installed expected. Maybe it would be interesting to:
- Check if something exist in `/opt/goenv/versions/` with the command `ls /opt/goenv/versions/`.
- If there are anything it could have been removed at the remove so doing a restore with the option `--no-remove-on-failure` would help to understand what what is the state of the golang installation when it crash.

Path seems wrong, right? Shouldn’t it begin with `/opt/goenv/versions/...` instead of the ‘system’ go installation path ?

yes but it’s a bit more complicated, because it should be added in case `/opt/goenv/versions/..` exist but it seem not existing, that’s why it’s not in the path.
