So, I installed 16.04 a few days ago and had to reinstall some apps. One of them was avidemux. After I installed it from the software center I couldn't get it to work properly. It wouldn't even load a video clip before giving me an error message and closing. After trying many command prompts to purge the avidemux files, I still can't get it to reinstall from the software center... Any tips?  I posted the question a few days ago and didn't get a response.

If i click on Ubuntu Software, it doesn't open. I have a fresh install of Ubuntu 20.04. I tried try to upgrade all packages, but it doesn't fix this problem.  If I try to run killall software-center there is no process with this name, and software-center returns command not found. If I try to reinstall it with apt I have these results:  $ sudo apt-get --purge --reinstall install software-center Reading package lists... Done Building dependency tree        Reading state information... Done Package oracle-java8-installer is not available, but is referred to by another package. This may mean that the package is missing, has been obsoleted, or is only available from another source E: Package 'software-center' has no installation candidate

Some kinda voodoo, indeed.  Bought a new boot drive, and it's time to use the old drive for data. I thought I'd save some time by just wiping the unneeded system folders, instead of backing up, formatting, and restoring. Wups!  I have a single Adobe file that absolutely will not be deleted. G:\Windows\SysWOW64\Macromed\Flash\flash9.ocx - though it may have started with a different file name. I'm able to rename it, oddly enough.  To be clear, the drive is currently plugged in externally. So I can boot the computer, plug this drive in afterward, and immediately attempt to delete. "File in use" box reads "the action can't be completed because the file is open in another program".  I'd format at this point, but it's my white whale, and I have to know if Adobe has inserted some nasty little registry hack - or whatever it is - making this impossible.  Since I'm sure it'll come up, I've taken ownership of the file - and this was the trick preventing me from deleting anything else on the drive - full rights on the file permissions, you name it, I've fiddled with the file itself.   I'm about to try uninstalling flash from the system drive, in case that aligns the planets properly. Sometimes I wish I were less stubborn, and could just format already.

I accidentally removed all the packages starting with the name jpeg with:  sudo apt-get remove jpeg*   This screwed up a lot of things, removed Unity, Firefox, Flash player etc.  I somehow managed to recover the desktop and unity but then a lot of things are still buggy. For example .rpm files and .tag.gz just won't open up at all.  What I want is a way to fix everything that's amiss. Something that is the equivalent of a 'repair installation' with a windows disc.  Any tips, anyone?

I got a new install of 18.04, and when I install en app from Ubuntu Software or snap it will not start. If I install the same app from a deb-package it works. What is going on? Kinda resembles a permissions problem or something...  Please help! :D

When I remove an application already installed through the Software Center. Does it remove the app the same way as doing a purge to it (aptitude purge) or does it remove it like a "remove" (aptitude remove).

I went to step 4 from  guide and extracted LAStools to my C drive and just made the folder there.   I can't do step 8 because it seems to already be in "advanced interface". Then, step 9 mine only says "Options".   Step 10 is where I get the error message and it won't go past that step. I keep getting this error message. Can anyone help me get this installed?

I've recently been trying to 'install' stuff a lot less on my Windows machine (I hate installers - I need to know where programs put stuff...), choosing to use portable or standalone versions of applications instead.  I put them all in a 'Programs' dir on a drive separate from my Windows partition, so whenever I reinstall, I have all my applications available with minimal effort and on the plus side, I get a nice clean setup.  Applications like Office and Creative Suite still require me to go through a horribly long installation process where a thousand random libraries and tools are thrown across my system.  Why do Windows apps still need installing? Why can't we just drag Photoshop to a folder à la OSX and just have it work? Does anyone else focus on portable apps, or am I just being OCD about the whole thing?

I found this page with some examples:   I'm wondering which one to use. Any suggestions? I'm using other packages too so whichever is less likely to interfere with them is better for me.

I started using Blender couple of weeks ago to edit some of my video clips. Spent quite a while editing this one, and everything worked fine. Video rendered as it should. The whole project consists of a MP4 file with a whole lot of soft cuts. Came back to it a couple days later and now the preview won't show a thing. When I render the scene, it's just a black screen with no sound.  The original file is still working, as well as my other Blender projects. And the weirdest thing is that if I add a new movie clip to the project, the preview works just fine for that clip.  Can anyone guess what might have caused this? I've googled like crazy and haven't found anything helpful.

Recently my Ubuntu Software Center could not be opened(it opens showing nothing and exit automatically). I therefore ran the command sudo apt-get remove software-center to remove the Ubuntu Software Center. then I use sudo apt-get install software-center to reinstall it.   Now I have two Ubuntu software Centers; one is called "Ubuntu Software"(default broken one), another is called "Ubuntu Software Center"(the current working one).   The problem I have is that whenever I want to download something not in the Software Center, if I open the .deb file, the broken one opens it, and closes very quickly. Basically I can't download anything outside the Ubuntu Software Center for that reason.   My current Ubuntu version is Ubuntu 16.04LTS.

Is it possible to copy all my applications from the applications folder onto an external, format my mac, reinstall OS X and finally copy the applications back into the applications folder for installing them?  Will that work? I am asking because my macbook seems to be behaving in a very odd manner, has become excessively sluggish and is preventing me from recording anything in logic.. I have tried the usual freeing up space, clean desktop, fixing permissions, verifying and repairing disk as well as resetting pram and making sure I have all the latest software and firmware updates. The macbook is only 8 months old and is running Lion with 8gb of ram, I really cannot understand what is wrong with it. Even when trying to watch a movie, the player will get serious audio/video synchronisation issues and I noticed that every time my wifi is on the fans speed up like a plane taking off. I even checked and it is clean from any dust. I am perplexed :(   If anyone could help me please, I would greatly appreciate it.  Thanks in advance!

Why is it sometimes that I need to restart my computer after installing new software and at other times I don't?  Is there any reason why it needs this reboot or why it's not always one way or the other?

Since , how do I uninstall it from my desktop system?  (Please note: This question is not about Unity 7, which is still supported at the time of this writing and should remain installed if present.)

In Ubuntu 17.10 I installed applications from the software center. At first everything worked fine, but after a few days they kind of disappeared. They are neither found when searching in the dash, nor when the executable name directly in the terminal. However, the software center shows them still as installed and they can be launched from there. Any help to fix this strange behavior is appreciated.

As time goes by we tend to do apt-get install and add or replace software.  Are these archived in some form or do they get auto-cleared after installation? And if it doesn't get auto-cleared, it would mean that a clean up is needed, isn't it?  Finally, if they're not auto-removed, can we reuse these packages on different machines?
