Hi,
bug confirmed on my side

5270 SUCCESS Backup deleted: shellinabox-pre-upgrade1
5270 DEBUG Checking that required services are up and running...

8157 WARNING Failed to deprovision system_user : Failed to delete system user for shellinabox

manually stopping the shellinthebox service before the upgrade did the trick.

[ericg]

Thanks for the feedback. Can you detail the action you did?

[thierry56]

Ewilly, stop the service and update shell in the box seem break the apps : the app seem well update but in the user panel, the big button disappear!(and impossible to start the shell in the box service).
I uninstall shell in the box and re-install, same things, the install seem well but no shell button in the user panel!!! where is the button? in terminal SSh work well

the log after re-install:

I also tried to stop the service and do the update: the update was successful, but then the service doesn’t start:
