uninstall vmware deleted lib files by mistake?

By not using the official way of removing software (see `man apt dpkg aptitude`), you have broken your system. Reinstall. Boot from an install CD/USB, and be sure to find and uncheck the "`Format`" boxes.

FYI: Your system keeps a list of what packages are installed; those installed packages means specific files were installed on the system. It won't re-install them by default (*no need as they're present according to the installed packages database*), but that database no longer matches what you have as you didn't remove using package tools. You can `apt install --reinstall` for each package that will cause the files to be re-populated if you know what exactly you removed; but a restore from backups, or re-install is usually the fallback if you don't know exactly what you removed.

i removed vmware packages from /lib so how i can use apt install --reinstall according to that?

also what is meant be reinstall? ive to reinstall format whole system and reinstall ubuntu? or reinstall vmware horizon

Packages & files are different concepts. A package can contain 1 or more files. Say you removed a single file (`/usr/share/doc/base-files/FAQ`) you can use `dpkg -S` to find out it's provided by [base-files](https://packages.ubuntu.com/focal/base-files) meaning that package would cause it to be restored. You didn't say what files you erased; thus why restoration of backups OR re-install were suggested first. My suggestion assumes you know what **exactly** was removed (ie. actual file detail). Inside a directory can many files, meaning many packages will need fixing...

Another option would be create a like system to look what should be there; and use that as a basis for what will likely need to be reinstalled (*I've done this before; as a learning exercise after I made a mistake... it took way longer than restoring of data or re-install; but doing it is a sure way to consider the consequences to subsequent & careless `rm` commands*...)

oh okay then acc. to this idk which files i removed there were 2-3 directories related to vmware in /lib i removed them all idk name or anything about them. so what should i do now?

when i again try to intstall vmware through gui installer it says already installed and terminal shows installation done

I mentioned that before; the package list says it's installed as you installed it earlier... thus the need to `install --reinstall` I covered earlier.

i ran this commnad nothing happened 0 upgraded, 0 newly installed, 0 to remove and 0 not upgraded. this is what came

Read back... I mentioned for each package that needs to be re-installed.. ie. in my base-files example it was `sudo apt install --reinstall base-files` which would cause the package `base-files` to be re-installed, a process you need to do for each package where you deleted libraries/files in the directory...

E: Unable to locate package VMware-Horizon idk the package name :( :(

You write that you "*can't install fresh*." That's too bad. A fresh install would quickly solve the problems that you created.

hi all the problem was solved without any boot from CD or anything like that...i simply entered my computer local folder as a super user i accidently files realted to vmware from /lib folder before so one by one i entered each folder like /etc /usr /bin etc. and deleted any files related to vmware with rm-rf command then i tried to reinstall vmware it was succesfully installed and running now.

I sit in a Tesla and translated this thread with Ai:
