failed apt-get install Reading package lists...

[joeck]

I'm getting this error when trying to deploy a python package to cloud foundry with apt-buildpack#0.3.0: Error running supply: failed apt-get install Reading package lists... Package has been up and running without issues on #0.2.11 but with cflinuxfs3 being deprecated I increased version to support cflinuxfs4.

What version of Cloud Foundry and CF CLI are you using? (i.e. What is the output of running cf curl /v2/info && cf version? cf version 8.6.1+b5a352a.2023-02-27

What version of the buildpack you are using? 0.3.0

If you were attempting to accomplish a task, what was it you were attempting to do? deploy mta python application to cf

What did you expect to happen? successful deployment

What was the actual behavior? deployment fails with error: Error running supply: failed apt-get install Reading package lists...

• Is the same version working fine on cflinuxfs3 and only failing on cflinuxfs4?
• Does the log contain more information like The following packages have unmet dependencies: or E: Unable to locate package X? Could you provide the full log?
• What's mbt build and mta.yaml? Is that descriptor for some commercial cloudfoundry flavor? I assume its just same as cf push?

thanks for your answer arjun. my bad on not updating this, I was able to resolve it myself

turns out the package libdc1394-22-dev was removed as mentioned here

changing to libdc1394-dev resolved the issue.

cheers
