I've been trying to upgrade my Ubutnu from 14.04 to 16.04, when I click on upgrading the system is shows me this error:

The required dependency 'apt (>= 1.0.1ubuntu2.13)' is not installed

I tried the sol here, but it didnt work with me: 14.04 --> 16.04 failed; apt (>= 1.0.1ubuntu2.13)' is not installed.

UPDATE:

I fixed the mentioned problem above, but still, I cannot upgrade to 16.04. Now is shows me this:

Error during update 

A problem occurred during the update. This is usually some sort of network problem, please check your network connection and retry.

They have been ignored, or old ones used instead.

Also, Google Chrome stopped working all of sudden. When I try to open it using the terminal, it shows me:

[8984:9017:0728/230608:ERROR:nss_util.cc(744)] Error initializing NSS with a persistent database (sql:/home/maldini/.pki/nssdb): libsoftokn3.so: cannot open shared object file: No such file or directory

[8984:9017:0728/230608:FATAL:nss_util.cc(214)] nss_error=-5925, os_error=0

Aborted (core dumped)

I removed and "purged" the program and then re-install again. I tried removing all the caches and config files. They all didn't work.

Any suggestions?

I had the same issue when im running google-chrome from terminal,

I found that it needed a new version of NSS: Chrome 62 need NSS>=3.26. So I installed libnss3.

$google-chrome

[6999:7036:1113/200616.549496:FATAL:nss_util.cc(632)] NSS_VersionCheck("3.26") failed. NSS >= 3.26 is required. Please upgrade to the latest NSS, and if you still get this error, contact your distribution maintainer.
Aborted (core dumped)

#sudo apt-get install --reinstall libnss3

and it worked for me
