Hi there!

Which version of rockstor are you using?
And what steps did you take right before the error occurred?

For me, I can confirm that a similar error is present many times in my error logs and I am using 4.5.8.
I don’t remember what I was doing at the time. I imagine it must have been something to do with Rockon stopping/running or uninstalling/reinstalling.
I should say that I never got the stacktrace popping up in the web UI, only in logs.

Seems to me this is one of the latest releases (considering the line numbers in the call stack), and this seems to be related to the update channel selection, but would want @JSL7717 confirm that.

@phillxnet what I find curious is, under which condition this part of the code would be called, as it seems to remove both testing and stable repos together?

Fundamentally, I suspect that the update check was running or if updates were triggered from the WebUI and in progress, for example, was running in the background, while @JSL7717 was trying to change the update channel, hence causing the error above, since zypper is busy with the other activity and locked.

Exactly that.
@JSL7717 , you should be ok retrying what you tried to do after a little while, time for the previous zypper process running in the background to be done.
