Issue in installing Veeam linux backup agent

[lorenzo06]

Dear all,
I am a beginner with ubuntu and I am trying to install Veeam backup linux agent on a vmphere virtual server.
My Ubuntu distibution is 16.04. I have been following the guide that Veeam provides ( https://www.veeam.com/veeam_agent_linux_1_0_user_guide_pg.pdf ) but I got stuck during the installation process because apitude gives me an error message regarding dependencies.

This is the code I receive when trying to install the software:


root@otrs:~# apt-get install -f veeam

I tried to look for a solution online but I was not able to find much.
A current solution that is proposed is to run apt-get update, apt-get autoremove, purge or other similar commands. However, none of these worked in my situation.

I hope you will be able to help. Thank you very much in advance for your help!

sudo apt-get install -f

Hi Xian,
thank you very much for your reply. I was able to solve the issue by using aptitude instead of apt-get. It seems that aptitute is smarter, it understand the problem and it proposes different solutions. Here is how I solved:


root@otrs:/tmp# aptitude install veeam
The following NEW packages will be installed:
dkms{a} fakeroot{a} gcc{a} gcc-5{ab} libasan2{a} libatomic1{a} libc-dev-bin{a} libc6-dev{ab} libcc1-0{a} libcilkrts5{a}
libfakeroot{a} libgcc-5-dev{a} libgomp1{a} libitm1{a} liblsan0{a} libmpx0{a} libquadmath0{a} libtsan0{a} libubsan0{a}
linux-libc-dev{a} manpages-dev{a} veeam veeamsnap{a}
0 packages upgraded, 23 newly installed, 0 to remove and 0 not upgraded.
Need to get 39.8 MB/39.9 MB of archives. After unpacking 115 MB will be used.
The following packages have unmet dependencies:
libc6-dev : Depends: libc6 (= 2.23-0ubuntu3) but 2.23-0ubuntu5 is installed.
gcc-5 : Depends: binutils (>= 2.26.1) but 2.26-8ubuntu2 is installed.
The following actions will resolve these dependencies:


Keep the following packages at their current version:
1) dkms [Not Installed]
2) gcc [Not Installed]
3) gcc-5 [Not Installed]
4) libc6-dev [Not Installed]
5) veeam [Not Installed]
6) veeamsnap [Not Installed]


Leave the following dependencies unresolved:
7) gcc recommends libc6-dev | libc-dev
8) libgcc-5-dev recommends libc6-dev (>= 2.13-0ubuntu6)
9) gcc-5 recommends libc6-dev (>= 2.13-0ubuntu6)
