For those who are sticking to KeePass2 password manager, here’s an Ubuntu PPA contains most recent .deb package for Ubuntu 24.04, Ubuntu 23.10, Ubuntu 22.04, Ubuntu 20.04, and Ubuntu 18.04.

Linux has a native KeepassXC password manager, though KeePass2 is still available for choice, which runs in Linux through Microsoft’s mono software framework.

Ubuntu includes KeePass2 package in system repository, but always old!

For the most recent versions, 3rd PPAs so far are the only choices besides building from the source tarball.

The most recent is KeePass2 2.57, features more secure options including Prevent certain screen captures option in “Tools -> Options”, and ability to create key files on secure desktop.

The release also includes some improvements, such as DPI detection, method for custom error handling/reporting, and auto-type compatibility with Remote Desktop Client (WSL).

Other changes in KeePass2 2.57 include:

• New keyboard shorcuts for for the ‘Copy Group (Encrypted)’ commands.
• Support for long paths when running on .NET 4.6.2 or higher.
• Automatically adjust weak key transformation settings to the current default values
• Save default to the KDBX 4/4.1 file format, use Export for old format.
• Supports all TLS/SSL protocol versions when running on .NET 4.7 or higher.
• See release note for details.
