Not able to upgrade ubuntu version 15.10 to 16.04

Question

First of all I am trying to upgrade php version 7.0 to 7.1 in ubuntu 15.10 and I asked the question but community closed my question and asked me upgrade ubunuu version so I asked this new question.

I think this is not duplicate question, as I tried all of the online solution but nothing worked so please check my output.

I am using Ubuntu version 15.10

I followed all of the links to change the /etc/apt/sources.list to http://old-releases.ubuntu.com/ubuntu from archive.ubuntu.com/ubuntu but nothing helps me

Possible duplicate of How to install software or upgrade from an old unsupported release? You need to also remove the lines in your sources.list from Ubuntu 15.04 (vivid) because you are upgrading from 15.10, not 15.04. — karel, Jun 03 '19 at 08:31
This is not duplicate please see my error now @karel , I don't know why my question is suggesting close ? — keyur, Jun 03 '19 at 08:33
What command are you trying to release-upgrade with? Did you just modify your sources yourself (with a search/replace) and then try and dist-upgrade? Ubuntu doesn't release-upgrade that way. — guiverc, Jun 03 '19 at 08:33
Yes, I modified the source by myself as I got some article that I need to change the URL with archive.ubuntu.com to old.release.ubuntu.com @guiverc — keyur, Jun 03 '19 at 08:39
Could you please explain how I can upgrade If I am doing wrong @guiverc — keyur, Jun 03 '19 at 08:50
Upgrading from 15.10 (or 14.04 LTS) to 16.04 is covered in the 16.04 release notes - https://wiki.ubuntu.com/XenialXerus/ReleaseNotes Note: it was tested using 16.04 as it was at release 2016, and was tested to continue to work in 14.04 LTS's lifespan, but 15.10 updates stopped long ago and thus your ~3 year past EOL may have added issues, so please consider @Kulfy's advice (removing 3rd party..) — guiverc, Jun 03 '19 at 08:55
Thank you so much @Kulfy just upgraded the version to 16.04 and now I am planning to upgrade it to 18.10, please add the answer so I can accept it :) — keyur, Jun 03 '19 at 10:30
@keyur I recommend you to stick to LTS version such as 16.04 and 18.04 instead of non-LTS release 18.10 to avoid upgarding every six months at least. 18.10 will go EOL next month. — Kulfy, Jun 03 '19 at 10:57
ok, thanks I will keep in mind and for the 18.04 I need to follow the same step? — keyur, Jun 03 '19 at 11:08

The repository information here looks malformed. It contains repository information of vivid (15.04), wily (15.10) and xenial (16.04). Since you are using Wily Werewolf (15.10), you need to restore default repository information of wily. Moreover wily is now EOL, so old-releases would work instead of typical archives. To restore default repository information for Wily (old-releases) use either of the two methods:

Remove old sources.list
```
sudo rm /etc/apt/sources.list
```
Recreate sources.list. I've pasted repository information (old-releases) here for convenience. Copy and paste repository information from there using
```
sudo nano /etc/apt/sources.list
```
Save and Exit.

OR

Open Software and Updates app, select components and click on save/reload. You might get failed to fetch repository information and that's quite obvious. Click OK and run
```
sudo sed -i -re 's/([a-z]{2}\.)?archive.ubuntu.com|security.ubuntu.com/old-releases.ubuntu.com/g' /etc/apt/sources.list
```

Now, ensure all packages are up-to-date before upgrading the system. For that run,

sudo apt update && sudo apt upgrade

Also, before upgrading system to a newer release, considering disabling all 3rd party PPA and removing all packages installed from that.
