sudo apt-get update

Next, to upgrade only the bands_FS.x, e.g. single package, you should use the following format with the apt-get command/apt command:

sudo apt-get --only-upgrade install quantum-espresso

Note that this command will not install any new packages! If you wish to install the package if it doesn't exist you may leave out --only-upgrade part.

sudo apt-get install quantum-espresso

How To Uninstall bands_FS.x from Ubuntu 22.04

Extra info and code examples

Quantum ESPRESSO (formerly known as PWscf) is an integrated suite of computer codes for electronic-structure calculations and materials modeling at the nanoscale. It is based on density-functional theory, plane waves, and pseudopotentials (both norm-conserving, ultrasoft, and PAW). Features include: * Ground-state single-point and band structure calculations using plane-wave self-consistent total energies, forces and stresses * Separable norm-conserving and ultrasoft (Vanderbilt) pseudo-potentials, PAW (Projector Augmented Waves) * Various exchange-correlation functionals, from LDA to generalized-gradient corrections (PW91, PBE, B88-P86, BLYP) to meta-GGA, exact exchange (HF) and hybrid functionals (PBE0, B3LYP, HSE) * Car-Parrinello and Born-Oppenheimer Molecular Dynamics * Structural Optimization including transition states and minimum energy paths * Spin-orbit coupling and noncollinear magnetism * Response properties including phonon frequencies and eigenvectors, effective charges and dielectric tensors, Infrared and Raman cross-sections, EPR and NMR chemical shifts * Spectroscopic properties like K- and L1-edge X-ray Absorption Spectra (XAS) and electronic excitations

Conclusion

You now have a full guide on how to install bands_FS.x using apt, apt-get and aptitude tools. Also, we showed how to update as a single package and different ways to uninstall the bands_FS.x from Ubuntu 22.04.
