Good Morning
Can you add KeyPass v 2.x to your apps list.
KeyPass v 1 is no longer suported on Linux Ubuntu and I must use now KeyPass v2.x with data base type kdbx.
I use it under Windows, Android and Ubuntu.
I have take it on portable version on :

Thanks
KeepPass 2.x in Windows is a .NET application and John is still working out how to support given the different versions of .NET supported by the different versions of Windows. And .NET may not be installed on a given PC and/or may require Administrator to install or update.
Already in the list of apps requiring external dependencies: https://portableapps.com/development/outdated

For Ubuntu I would recommend KeePassX (originally developed as a Linux port of KeePass, but is now cross-platform itself).
I use KeePassX 0.4.x on Ubuntu and KeePass Portable 1.x on Windows, with the db shared between the two using Dropbox, and have never had any compatibility problems with the db.
