Ubuntu – Apt-get install behind proxy – Failed to fetch

18.04aptPROXYupdates

This is yet another question regarding the error message E: Failed to fetch ... (example in Note 2 below).
What makes this question different (I guess) from the others I have seen is the following.

I am running Ubuntu 18.04LTS, behind a proxy.
I had a lot of packages with available updates (more than 200, I guess).

    I could update many of the packages with no problem, and I ended up with 48 that I cannot install.

All of the packages not installed belong to bionic-updates/universe or bionic-updates/main.
And most are related to java, jdk, linux, systemd.
The complete list is in Note 1 below.
But there are packages from bionic-updates/universe and bionic-updates/main that I can install (I just installed qemu and bsdutils).

How is it possible that some of the packages can be installed and some cannot?

What is a possible solution (other than connecting the PC without a proxy)?

This was obtained with

$ sudo apt list --upgradable 2> /dev/null | sed 's/\/.*//' | tail +2 | sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/ /g'

To find which repo each one belonged, I used (printf "%30s"... helps visualizing in columns)

$ for p in $(sudo apt list --upgradable 2> /dev/null | sed 's/\/.*//' | tail +2 | sed -e ':a' -e 'N' -e '$!ba' -e 's/\n/ /g') ; do printf "%30s" $p ; apt policy $p 2> /dev/null | tail +6 | head -1 ; done

This generates output like

  • It looks like enterprise firewall is blocking certain urls of apt, that's why you are not able to download packages via apt. You need to get all URLs white listed in firewall mentioned in source list. You need to have admin access of firewall or kindly contact network administrator.

    As Alternative option, try to connect system directly with another internet source like USB Dongle or Mobile.
