GLIBC_2.34 is required to run just (that's because native images built with GraalVM require it). It does work on out of the box on Ubuntu 22.04 LTS.

Hi Maciej, Thanks for the prompt response. I upgraded to Ubuntu 22.04 LTS. Installation was succesfull. but now each command ends with an error below. I searched over google for error but cant find anything concrete.

Just starts server on random available port. I am not sure what is happening but it seems like it picked a port that is already taken? Can you try to run it again (different port will be used) or force port with:

$ JUST_SERVER_PORT=8082 just -V

[xerverless]

Hi Maciej, I tried running the below command as is -

• JUST_SERVER_PORT=9991 just -V As well after exporting the environment variable
  • export JUST_SERVER_PORT=9991
  • just -V

Still getting the same error. will do more google and try to get some solutions. Thanks for the help. will paste the solution here if able to resolve it. Looks like it is not related to port but something else.

I have also this error on Mac M1.

@MaxWenzel i assume it happens with random port too? Can you check if the port it selects is already taken?

[MaxWenzel]

You are right, it seems to be a problem with the port. If I use

JUST_SERVER_PORT=6060 just run

I cannot reproduce it but I get the next error: Issue-50
