Accidentally broke Ubuntu 16.04 by removing python 3 :( Apache2 and LetsEncrypt broken - how can I fix?
I was trying to install Octoprint on Ubuntu 16.04 for my 3D printer, but I was having problems with the installation as it needed Python 3.6 and I only had Python 3.5
I searched how to install Python 3.6 on Ubuntu 16.04 and after various methods I managed to do install it and also managed to install Octoprint, although Octoprint would not run due to some errors.
Then I found that terminal in Ubuntu desktop would not work and after searching I found a website explaining how to fix it, using the following commands...
cd /usr/bin
sudo apt-get purge python3
sudo rm python3
sudo ln -s python3.5 python3Source:
The worry started when I could see it deleting lots of things which took around 5 minutes and when I opened Ubuntu desktop half of the icons were missing.
I managed to sort of fix it by running:
sudo apt-get install python3-allI am now considering a fresh install this time using Ubuntu 20.04, as well as fitting larger HDD's in my server (Dell Poweredge T30) using RAID5.
However, I run Nextcloud on the server and dont want to loose the data stored in Nextcloud, but I cant access Nextcloud because Apache2 doesnt work anymore. Somehow the live folder of LetsEncrypt seems to have been deleted since removing Python3.
If I run...
systemctl status apache2.serviceI get the following error...
apache2.service - LSB: Apache2 web server Loaded: loaded (/etc/init.d/apache2; bad; vendor preset: enabled) Drop-In: /lib/systemd/system/apache2.service.d └─apache2-systemd.conf Active: failed (Result: exit-code) since Thu 2021-01-14 20:25:00 GMT; 11s ago Docs: man:systemd-sysv-generator(8) Process: 1140 ExecStart=/etc/init.d/apache2 start (code=exited, status=1/FAILURE)

When I try to restore the backup of /etc/letsencrypt there is still no live folder, the only folders are:
- csr
- renewal
- renewl-hooks
How can I get Apache2 working so I can get Nextcloud back online ?
The backup tool is configured to backup the entire root folder, I did try to restore the root folder from a previous backup but it crashed and I had to power cycle the server.
In future I need to fix this backup issue because it has let me down in this instance.
