Some other package you want to install may have dependencies that conflict. As long as the package remains, so does its dependencies. Besides recovering the disk space, it reduces the chance of problems. If you then decide you don't need it, uninstall it. If you want to evaluate packages that look interesting, wait to install it until you're ready to actually try it. Load one or two packages and verify that everything is working. This Xubuntu-specific shortcut will also launch Terminal. Load what you know you need, and do it in increments. 1 2 Press Alt + F2 and type gnome-terminal. But don't just load a whole bunch of stuff that looks interesting. Ctrl + Shift + T > New terminal tab If you use above combination, you can open terminal tab on same window. For this to work, you should already be on the terminal window. You will need a storage location for its backup files. Ctrl + Shift + N > New terminal window This shortcut can be used to open a new terminal window. If everything is working, set up Timeshift, which makes it easy to recover to a working system if things go sideways. The first step after you install should be to run updates.
The farther you venture from the repository, the more likely you are to encounter problems. Those are safe in terms of not messing up your system, but not all of the applications work flawlessly out-of-the box. Mint supports Snap and Flatpak applications. Ubiquitous packages like major browsers and office suites are usually pretty safe to install from the developer's web site, but you're taking risks installing something not mainstream. You are generally safe using the Ubuntu LTS repository, as well, since Mint is based on Ubuntu LTS and already draws from there.Īdd packages from PPAs with caution try to stick to ones that are widely recommended, and don't have reports of issues. The simplest way to do this is to pipe the output of the netstat command to the grep command. Try to stick with what's in the repository because those packages will have been tested with the distro and possibly customized to work well with it. Listing Open Ports Before opening a port on a system, check if the port you need is already open.

This video, How to Upgrade or Reload Linux while Keeping Your Data, might be useful in understanding how to use a separate home partition to reinstall or upgrade without losing your data.īe organized and careful in installing packages. The separate root and home partitions will simplify backup, upgrading, and recovery from stuff like this. The swap partition will improve performance. Put root and home in separate partitions, and have a swap partition. If you installed Mint in a single partition, use three partitions, instead. But when you reinstall, there are a few things you can do to reduce the chances of this happening again, or make it easier to recover if it does. If you have important files, back them up, then start from scratch. On the positive side, since you haven't used it for too long, you can start over without it being too traumatic. Unfortunately, there are too many possibilities for people here to be able to figure out what the specific cause is. Needless to say you can increase the rate further ( -L 8000), and the command becomes very similar to cat, with the output appearing instantaneously.įor more information see man pv or the Ubuntu manpages online.The technical term for that is "your system got hosed". This should help : ls -l /usr/bin/python3 lrwxrwxrwx 1 root root 10 May 31 13:02 /usr/bin/python3 -> python3.10 You might need to install python again to get the binary. The example below uses a high rate (300), but if you choose a low rate such as -L 50, it will appear as if the computer is typing out the file for you. 1 It is because /usr/bin/python3 is a soft link to /usr/bin/python3.10 which is the main binary that runs python3 on your machine.
With pv you can literally print the file to the screen, and choose the rate ( -L) at which it appears.
Monitor the progress of data through a pipe.pv will copy each supplied FILE in turn to standard output (- means standard input), or if no FILEs are specified just standard input is copied. It is in the repositories and so can be installed with sudo apt-get install pv if you don't have it already.Īs the man page notes, pv is very often used to As we seem to be listing all available alternatives of displaying any text file in the terminal, it would be quite fun to introduce pv as technically one valid (but unusual) method, although I would normally use cat instead for most things.
