Indeed, --quilt=dpm works fine. dgit already has logic to try to spot when you have passed the wrong --quilt option and tell you what it thought it maybe should have been. > I suggest that, at least, it would be helpful for dgit to notice the > situation where (1) there are quilt differences; (2) --quilt= other than dpm> was explicitly specified; (3) debian/.git-dpm exists. > It could then include something in the error message suggesting to the > user that they should probably omit --quilt= or use --quilt=dpm instead, > or something along those lines. This is a useful suggestion. But also I want to see why the existing quilt mode guessing code didn't make a useful suggestion in your case. Thanks, Ian. -- Ian JacksonThese opinions are my own.

Bug#928365: dgit: more helpful error when --quilt=gbp but you meant --quilt=dpm?
Source: dgit Version: 8.4 Severity: wishlist I did this in one of my packages (https://salsa.debian.org/debian/spectemu 98b1b3de26fc9e7b5e857eeb5bf83d0d526c4001, if it matters): $ dgit -wn --quilt=gbp quilt-fixup Format `3.0 (quilt)', need to check/update patch stack examining quilt state (multiple patches, gbp mode) gzip: warning: GZIP environment variable is deprecated; use an alias or script dgit: split brain (separate dgit view) may be needed (--quilt=gbp). dgit: base trees orig=b3aecce5e4a6e0caf8ae o+d/p=d27d28aa8170e9d16e66 dgit: quilt differences: src: ## orig ## gitignores: == orig == dgit: quilt differences: HEAD == o+d/p HEAD == o+d/p dgit: error: --quilt=gbp specified, implying patches-unapplied git tree dgit: but git tree differs from orig in upstream files. dgit: For full diff showing the problem(s), type: dgit: git diff b3aecce5e4a6e0caf8ae881a84e3c62de0507c23 HEAD -- :/ ':!debian' ':!/.gitignore' ':!*/.gitignore' On inspection of the diff I saw that it was basically just a combined version of my debian/patches/ and so I was a bit confused for a few minutes. Actually the problem was that I'd retrieved this dgit command line with C-r in bash and hadn't completely paid attention to the --quilt option there, and this branch uses git-dpm and so is a patches-applied branch. dgit(1) tells me: If you have a branch like this it is essential to specify the appropriate --quilt= option! This is because it is not always possible to tell: [...] So I dutifully got into the habit of using a --quilt option, and I understand that it makes sense for dgit to follow my explicit (if incorrect) instruction. However, in this case it *is* possible to tell, at least with good probability: debian/.git-dpm exists, so --quilt=gbp was probably a mistake. Indeed, --quilt=dpm works fine. I suggest that, at least, it would be helpful for dgit to notice the situation where (1) there are quilt differences; (2) --quilt= was explicitly specified; (3) debian/.git-dpm exists. It could then include something in the error message suggesting to the user that they should probably omit --quilt= or use --quilt=dpm instead, or something along those lines.
