Ubuntu/Mint PPA contains wrong version

[FBachofner]

When adding the PPA indicated at https://dosbox-staging.github.io/downloads/linux/
to LinuxMint 20.3, apt-get install dosbox-staging installs version 0.76.

Launchpad indicates the PPA shoud install 0.78.1

apt-cache policy dosbox-staging

yields the following:

dosbox-staging:
Installed: (none)
Candidate: 0.76.0-1+ubuntu20.04
Version table:
0.76.0-1+ubuntu20.04 500
500 http://ppa.launchpad.net/feignint/dosbox-staging/ubuntu focal/main amd64 Packages

Launchpad itself is not letting me log in with my UbuntuOne credentials, so I am reporting here after initially posting to dosbox-staging

Sorry in advance for this duplication

I saw that the missing dependency is available here. https://launchpad.net/~feignint/+archive/ubuntu/munt/+packages
But Launchpad does not know it!

Please add that PPA as a dependency of the dosbox-staging PPA.
Open "Edit PPA dependencies" page in the dosbox-staging PPA and add the munt PPA there.
