In that case your version was wrong. ... The format is: [epoch:]upstream_version[-debian_revision]. ... The upstream_version may contain only alphanumerics [6] and the characters . + - ~ (full stop, plus, hyphen, tilde) and should start with a digit. If there is no debian_revision then hyphens are not allowed. https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-version So it should have been v1.0-rc3-deb0, or v1.0+rc3 ... It is a bug in your layer not in Isar. Henning > Jan >
