Help! Tar is missing
 
Hi, I've been running Mint 17 for some time now. Somehow, now it seems, that Tar is missing from my system. I've tried loading it from Terminal, from Software Manager, and from Synaptic Package Manager, all fail. This is preventing me from downloading other software that I need including JDK,JRE Oracle Java8, and Oracle virtualbox. In the Synaptic Package Manager dpkg shows, Broken dependency due to missing Tar. Does anyone know how to fix this problem? Thankyou!!!

Following is the Terminal history I get when trying to install it:

jack@Built-by-Jack ~ $ tar
The program 'tar' is currently not installed. You can install it by typing:
sudo apt-get install tar
jack@Built-by-Jack ~ $ sudo apt-get install tar

The following package was automatically installed and is no longer required:

Use 'apt-get autoremove' to remove it.
Suggested packages:

The following NEW packages will be installed:

Note: root's PATH should usually contain /usr/local/sbin, /usr/sbin and /sbin

when I try to install Tar from Synaptic Package Manager it fails with this MSG.

Post the output of the following:
Code:

sudo which tar
sudo echo $PATH

The tar command is usually located in /bin in Debian based systems like Mint. If it's not there and won't install you can take a look at this similar post where the guy solved the problem by copying tar into /bin from another working ubuntu system:

Thanks so much Kilgoretrout, It looks like exactly the same problem. On my system there is no tar in Bin, like theirs. however, they had another working system to copy it over from, they solved it doing that copy. I don't have another Linux machine around. More Suggestions! Best,

Hi...

If you would, please post the results of the command kilgoretrout mentioned. ;)

Regards...

You missed half the output message:
dpkg: warning: 'tar' not found in PATH or not executable
Have you checked permissions on /bin/tar ?

jefro 02-04-2016 03:41 PM

Agreed. " checked permissions on /bin/tar ?"

May be in some odd location too. Maybe use find -name from /

Some other program may be installed to do a similar task but that isn't what you wanted.

He said he already looked in /bin and tar was not there. To be doubly sure run and post the output of:

Code:

$ sudo find / -name "tar"
If "/bin/tar" is not in the output of the above command, tar is not there, just like in the ubuntu thread I posted earlier. If you don't get a location for tar in another location in the above output, it's nowhere on your system. I think that will be the likely outcome here, but I would like it clearly established before continuing.

Well, at first he did, then

I'm confused.

I just wanted to point out that 1\2 the error message was being ignored. :)

I understand, but if tar is not there(likely), it's not a permission problem. If it is we can check to see if tar has executable permission.

If tar is not there and won't install, the next step would be to download the tar deb package and try to force the install with dpkg like so:

Code:

$ sudo dpkg -i --force-all <tar deb package>

Gonna be a tough one as dpgk is depending on it...
dpkg: warning: 'tar' not found in PATH or not executable

Download it:
Code:

sudo apt-get download tar
the force-all hopefully will work. ;)

and if it doesn't, depending on the arch, a straight copy from a similar LM system may also work.

OK. Next, you want to download the tar package from the repo with the command Habitual gave you above, namely:
Code:

$ sudo apt-get download tar
That should download the tar package to /var/cache/apt/archives/ and not attempt to install the package. Actually, it might already be there from your last failed install attempt. You might want to check that first. If you are running 64bit, the tar package will have a name like "tar_1.27.1-1_amd64.deb"; if 32bit, the tar package will have a name like "tar_1.27.1-1_i386.deb". The version numbers may be different but the package names will be something like that. Once you get the tar deb package successfully downloaded, run the following:
Code:

$ cd /var/cache/apt/archives/
$ sudo dpkg -i --force-all <insert name of tar deb package>

If it refuses to install, post the error output.
