[Question] zip is not installed on server

[jemin-hwang]

I am currently working on our server.
When I run ./scripts/submit.sh, I get the following error message:

./scripts/submit.sh: line 4: zip: command not found
./scripts/submit.sh: line 5: zip: command not found
./scripts/submit.sh: line 6: zip: command not found
./scripts/submit.sh: line 7: zip: command not found

I remember I got the same error message before, and I resolved it by manually installing zip by sudo apt-get install zip.
But it seems that it does not work for this time:

ubuntu@CS431:~/cs431/homework$ sudo apt-get install zip
Reading package lists... Done

The following additional packages will be installed:

Sorry for the inconvenience. Can you create another workspace and try it again? I guess it will now work.

zip: command not found still occurred for a new workspace, but sudo apt-get install zip worked for this new workspace!
Thanks.
