I don't have neither Ubuntu, nor Fedora (as listed in the requirements) and no intentions of switching to either.

I do have debian, on which Ubuntu is based, and I do have a much newer debian than what Ubuntu 18 is based on (debian 13 "trixie", the current debian stable, which was released on August 9 2025).

The Dropbox debian package for Ubuntu has worked well for me on debian stable, since at least 2016, and still works.

But I am currently getting daily nags from debian APT because the APT archive of the debian package is signed which SHA1, which is not considered secure anymore, and because of this debian APT (and possibly later Ubuntu APT as well...?) will start rejecting the archive in less than one year.

So what you should do(and that you should do in any case...) is to upgrade the key used for signing your APT archive.

I.e. no changes to the code, just a change to the archive (including resigning of the packages, I guess...?).

Thanks for your update here, steinarb.

I'm afraid that if the minimum system requirements are not met, issues like this are kind of expected.

I did, however, pass your comments and feedback along to our team about this.
