[SOLVED] Uninstalling unwanted PHP and mariadb packages [WAS Re: How could the missing MySQL extension required by WordPress be installed?]
For all the debian-users who might fall into the same ditch into which I had fallen, to alert them ... I thank Mr. Cater for his advice at https://lists.debian.org/debian-user/2023/11/msg00443.html. I raed his advice and understood that while uninstalling I should follow a path chronologically reverse to the one I had followed while installing all those packages on the 10th Nov 2023. So what I did was that I noted down his advice on a plain text editor, then opted for "uninstall completely ..." the following packages: php-common apache2 apache2-bin apache2-data mariadb-client-10.5 Following my practice of safety, I kept a note of the packages I had installed, as recorded in my first post of this thread, at: https://lists.debian.org/debian-user/2023/11/msg00384.html as follows: [quote] The nearest that are available in Debian Bullseye : default-mysql-server default-mysql-server-core php-mysql php7.4-mysql apache2 php-db along with their dependencies. I installed them all. ... [/quote] Then I went to my list of synaptic installation history and from the block categories described earlier in: https://lists.debian.org/debian-user/2023/11/msg00411.html, individually selected the still unselected packages. All of them, listed on the History list of 10th November 2023. With a little anxiety, I proceeded for a complete uninstallation. The Uninstallation completed without an error message (synaptic reported in the "Changes Applied" window: "Successfully applied all changes...") as follows: [output] (Reading database ... 270111 files and directories currently installed.)

[/output] So a SUMMARY becomes due: To note down the bulk packages while installing, follow a path chronologically reverse to the one followed during installing, then from the "History of installed, upgraded and removed packages" also select the associated packages installed along with the bulk packages and remove them together at one shot. So thank you all

I am not posting an excuse, but sometimes, the excitement of the prospect of a new perspective and more wisdom becomes too overpowering to restrain myself from undue risk-taking. A millennium of lost opportunities, trampled hopes and prospects, the lack of a beautiful and fulfilling community life and a prosperous society enhances the excitement exponentially. In this regard we share our common pain with the Israelis, suffering from multiple-centuries of genocide even many times more than the 2nd World War Holocaust. Our foodgrains were repeatedly diverted, causing many man-made famines for more than a century, killing and displacing my ancestors and made us more susceptible to diabetes and heart diseases. But as the Israelis also endorse, the only people that didn't persecute them were us. My conscience cries for the sufferings of a grand continuous civilisation and her peoples, Mr. Cater. Prof. C K Raju's articles entice with the prospect of identifying the real perpetrators of such inhuman atrocities with more evidence. So the excitement couldn't be contained. > "I want to do X.

But in excitement I couldn't restrain myself from experimenting. I didn't consider the problem to be so irritating. So I didn't consider that I would have to ask for support later.

For the Mailing list, any change of subject from my Gmail webmail email-server makes such an email detached from the main thread and treats it as a different subject. Had Mailman also had an email editor for posting messages, that would have been a better option. However, I understand the difficulties and the legalities associated with this added functionality and acknowledge the associated problems, since FSF has to bear with the Deep State more, bringing an added peril to itself. We already know the fate of Assange, Snowden and myriads of unknown others. In countries where the Law owes its existence to Xtian Morality legitimising flat earth, land grab, usurpation, genocides, may the real Hive Mind of the Holographic Universe, the Brahm, save us from the faux construct. The people who choose to empower us, despite facing all perils, have our fullest admiration and wellwishes. Between the two opt

Then perhaps an apt-purge apache2 .. and so on. Then go back and remove any outlying packages that have not already been removed until you have no more left. For the future - for any reader of this list, not just Rajib: If you don't know quite what you're installing and a single package installs lots of other packages, stop and consider before you install. Meta-packages like desktops pull in lots of dependencies, but so, as you've seen does PHP If you're really not sure: read lots then ask. If you say "I want to do X. I think that means I need to install Y and configure Z. >From reading ABC pages, I _think_ that means that I need to do the following but I'm not sure because page C says to do this and I don't understand. I'm running Debian 12.2 updated this week. " - it becomes a lot easier to understand what you want. If you explain _exactly_ what error messages you get and how you get them that helps significantly. If you've done a web search and found a possible answer or that other people have had a similar problem, add that in. "I'm getting error message DEF from running this command. From the net, it looks as if other people have been having similar problems on older versions of Debian but not recently - am I reading this correctly" It shows that you have made an attempt to problem solve for yourself and people will be more willing to help and explain their suggestions. If the advice you get solves a problem - post that back to the list in the thread and change the message subject slightly to make it clear that this is an answer. For example: [SOLVED] Package foo fails to install in Debian 12.2. [Was: Cannot install foo] It is always possible that no-one else has ever seen anything similar. The advice you get from people here may always be a best guess as to a solution. The more clearly you can give information, the easier the problem solving becomes. If you have to ask lots of questions around the same subject, consider stopping and writing a summary post to write down what you've learned and solutions you have tried so far. SUMMARY - Package bar still failing to install after several tries "I have been given solution A in a post in this thread on November 1st. I did this but then got error message B - see post on November 3rd so I did C on November 4th. The problem I have now is that the error message is DE" Hope this helps, Andy [amaca...@debian.org]
