Getting error message: pristine-tar: delta is version 3, newer than maximum supported version 2

Asked by Thomas Karl Pietrowski on 2017-11-08

Due to an bug inside Ubuntu's patched PyQt5, I wanted to rebuild a more recent PyQt5.
I imported it from debian's repository and created an recipe (

However, when building from these sources, I get the error:

Git version:

when trying to build the source package. But I have no idea, how to correct the "pristine-tar: delta is version 3, newer than maximum supported version 2" issue. Are my recipe instructions wrong or is there something else?

Looks like we'll need to upgrade to a newer version of pristine-tar to get this to work, since there are versions in Debian with higher format numbers for some types of deltas. Could you please convert this question into a bug?

Thanks Colin for your answer. On which project shall I put the bug report? Launchpad again?

Colin Watson (cjwatson) said : #3

Yes - if you use the "Create bug report" link on the web UI view of this question, it'll do roughly the right thing.

Getting Timeouts here when trying to open a new bug report :(

Colin Watson (cjwatson) said : #5

Those do happen occasionally but are usually transient; give it a try in ten minutes or so. (Or possibly slightly longer - we're doing some large DB index rebuilds at the moment so load is probably a bit higher than usual.)

Converted to a bug :)

Thanks! I forgot about trying to create a new one already!

Colin, do you have a rough ETA for this bug?
