Hello Mate,

Hope doing well,

1.Can you check the below command that its having the command existence :

`ls /usr/bin/unminimize` 

2. If not, another possibility check : are you running the same dbr when it worked last time and now ? 

If not there might be databricks has fixed or removed this completely in new dbrs. 

3. if possible you can try below code in the community edition to update the ubuntu config: 

wget <ubuntu-repo-url>/unminimize
chmod +x unminimize
sudo ./unminimize

Please ignore if this might not help.

Thanks for the ask.
