Linux Mint update manager issues a warning or error during installation.
Linux Mint update manager issues a warning or error during installation.
The error indicates a problem during the package installation process. The command failed with exit status 2, which typically means a critical failure occurred, often due to missing dependencies or configuration issues.
You should apply the do-release-upgrade for that. Unless Mint doesn't support it (which is rare), you might need to run apt-get dist-upgrade instead.
