Karthik Nadig (@karthiknadig) it should have the correct permissions when we create it right? What user permissions do we check and setup the executable using?
GeraldTgl commentedon Oct 6, 2025
I would expect the execute permission is added during build looking at the following lines but somehow it seems this step is not running anymore?

Don Jayamanne (@DonJayamanne) do you know if this is something on the PET side?
DonJayamanne commentedon Jan 5, 2026
There's nothing that needs to happen on PET side, PET will only create the executable.
Setting permissions (if required) needs to be done by Python (or other extensions) that distribute PET
Also changing permissions in builds is not going to work, as these permissions are applicable ONLY for the machine on which
chmodwas executed on.Feels like something else is going on, else every user should be running into this issue.

hm its a good point. GeraldTgl are you on a remote machine with stricter settings or maybe a enterprise managed machine? Worth determining what about your setup would cause this problem to arise for only you

Because we have not heard back with the information we requested, we are closing this issue for now. If you are able to provide the info later on, then we will be happy to re-open this issue to pick up where we left off.
Happy Coding!

Apologies for the delay. This happened on RHEL 8 VMs that are enterprise managed through Puppet. Multiple users reported this issue and I was able to reproduce it at the time. In the mean time I do not work for this customer anymore and don't have access to their systems.
