Package 39;p7zip-rar 39; Has No Installation Candidate

[Cristhian Cinq-Mars]

Background:
I am doing a project in which I am benchmarking various platforms from across the 2000s using 7zip compression/decompression benchmark. I have been running Mint 19.3 XFCE 32 bit to benchmark all of the other systems but want to benchmark a system with an Athlon XP 3200+ for comparative purposes. Mint is unable to boot on this hardware, I believe because K7 is lacking support for SSE2 or some related instruction. I have gone through some attempt and failure with other distros which has led me to where I am at currently.
The problem:
I have installed Q4OS Gemini Trinity 32 bit and am writing from this machine. The installation does not seem to include 7zip preinstalled which is fine, however I am having issues when I try to install it. I have looked at another post from this forum which seems to say 7z should be preinstalled but I am not seeing this I have not had much success attempting to install it. When I try sudo apt install p7zip I get the error that the package has no installation candidate. I have tried a few different abbreviations for 7zip but cannot get anything to install. I assume I am overlooking something very simple, but need some guidance. Thanks!

The original 7-Zip is indeed available for Windows only. Its port to Linux is p7zip. I had no problem to install it on my x64 machine and it is available for i386 as well.
Did you try first to update the database of available packages?

The base package to install is p7zip. Other packages (p7zip-full and p7zip-rar) add more archive formats. Note that it is a command-line only application, no GUI is included.
Alternatively you can consider installing wine, which enables to execute Windows applications, to be able to install and run the original 7-Zip with its GUI.

If, as I suppose, you are new to linux, I encourage you to make your first steps with the "Command line interface" (CLI), i.e. using the terminal.
One valuable thing to know, is that most commands one can issue in the CLI can be used to get help on how to use them. For the p7zip command, for example, simply type after the command prompt ($)

If you prefer using a "Graphic User Interface" (GUI), you might consider using Ark. If you right-click on a zip file, Ark is likely to be an option to open it. I believe that p7zip isn't enabled by default in Ark. To enable it, in ark menu:
- Configuration > Configure Ark... > External modules
- check P7zip

Let me try to ask a desire to Q4OS Team. It would be very desirable to have a bit more apps in the application gallery, more browsers, file compressors, wine,... because on the console, not all apps work. Thank you.

Almost all applications, which are compatible with Debian Bookworm will work on Q4OS Aquarius. You can look in their websites for their compatibility with Linux Debian. For example SoftMaker FreeOffice:
Also, you can install Synaptic Package Manager from Q4OS Software Centre, and install necessary applications from Synaptic.
Just keep in mind, that nowadays, a lot of applications does not work on 32-bit hardware!

Yes this is correct. I should mention that I built SWI-Prolog roughly the same way (might have installed more or less of the required packages for a full build) just a few weeks ago and was able to pack_install(reif).

Somehow it cannot find even a candidate directory for installing the packs. These are installed into the first writable directory produced by pack(.). If no such directory exists it will try to create one. This is done by pack_create_install_dir/2 in library(prolog_pack).

Having not even candidates (which I think is the case because the message is printed as unknown message while it normally prints the candidates) is quite weird. Did you retract clauses for file_search_path/2? Try

The xcb plugin now requires way more libraries that might not be on minimal installations. I would recommend running with LD_DEBUG=libs to see what fails to load and installing the packages for those. The Fedora list includes:

Point the command at some music: directories, single files, orcompressed archives. The music will be copied to a configurabledirectory structure and added to a library database. The command isinteractive and will try to get you to verify MusicBrainz tags that itthinks are suspect. See the autotagging guidefor detail on how to use the interactive tag-correction flow.

Relatedly, the -q (quiet) option can help with large imports byautotagging without ever bothering to ask for user input. Whenever thenormal autotagger mode would ask for confirmation, the quiet modeperforms a fallback action that can be configured using thequiet_fallback configuration or --quiet-fallback CLI option.By default it pessimistically skip``s the file.Alternatively, it can be used as is, by configuring ``asis.

If you already have a metadata backend ID that matches the items to beimported, you can instruct beets to restrict the search to that ID instead ofsearching for other candidates by using the --search-id SEARCH_ID option.Multiple IDs can be specified by simply repeating the option several times.

The -L (--library) flag is also useful for retagging. Instead oflisting paths you want to import on the command line, specify a querystring that matches items from your library. In this case, the-s (singleton) flag controls whether the query matches individual itemsor full albums. If you want to retag your whole library, just supply a nullquery, which matches everything: beet import -L

You can use the -a switch to search for albums instead of individual items.In this case, the queries you use are restricted to album-level fields: forexample, you can search for year:1969 but query parts for item-level fieldslike title:foo will be ignored. Remember that artist is an item-levelfield; albumartist is the corresponding album field.

When you run the remove command, it prints a list of allaffected items in the library and asks for your permission before removingthem. You can then choose to abort (type n), confirm (y), or interactivelychoose some of the items (s). In the latter case, the command will prompt youfor every matching item or album and invite you to type y to remove theitem/album, n to keep it or q to exit and only remove the items/albumsselected up to this point.This option lets you choose precisely which tracks/albums to remove withoutspending too much time to carefully craft a query.If you do not want to be prompted at all, use the -f option.

When you run the modify command, it prints a list of allaffected items in the library and asks for your permission before making anychanges. You can then choose to abort the change (type n), confirm(y), or interactively choose some of the items (s). In the latter case,the command will prompt you for every matching item or album and invite you totype y to apply the changes, n to discard them or q to exit and applythe selected changes. This option lets you choose precisely which data tochange without spending too much time to carefully craft a query. To skip theprompts entirely, use the -y option.

This will scan all the matched files and read their tags, populating thedatabase with the new values. By default, files will be renamed according totheir new metadata; disable this with -M. Beets will skip files if theirmodification times have not changed, so any out-of-band metadata changes mustalso update these for beet update to recognise that the files have beenedited.

The -f option forces a write to the file, even if the file tags match the database. This is useful for making sure that enabled plugins that run on write (e.g., the Scrub and Zero plugins) are run on the file.

By default, the command calculates file sizes using their bitrate andduration. The -e (--exact) option reads the exact sizes of each file(but is slower). The exact mode also outputs the exact duration in seconds.

With the --edit option, beets attempts to open your config file forediting. It first tries the $EDITOR environment variable, followed by$EDITOR and then a fallback option depending on your platform: open onOS X, xdg-open on Unix, and direct invocation on Windows.

-c FILE: read a specified YAML configuration file. Thisconfiguration works as an overlay: rather than replacing your normalconfiguration options entirely, the two are merged. Any individual options setin this config file will override the corresponding settings in your baseconfiguration.

-p plugins: specify a comma-separated list of plugins to enable. Ifspecified, the plugin list in your configuration is ignored. The long formof this argument also allows specifying no plugins, effectively disablingall plugins: --plugins=.

You will also need to source the bash-completion script, which is probablyavailable via your package manager. On OS X, you can install it via Homebrewwith brew install bash-completion; Homebrew will give you instructions forsourcing the script.

If you use zsh, take a look at the included completion script. The scriptshould be placed in a directory that is part of your fpath, and notsourced in your .zshrc. Running echo $fpath will give you a list ofvalid directories.

Developers & Cardano stake pool operators generally need an air gap environment in which to work with payment keys, stake pool keys and other cryptocurrency resources that offer high-value targets for hackers.

Some specialised hardware (e.g. hardware wallets) may also perform this function. If you believe you have such a device, please be certain that it offers isolation features for your stake pool or development and that you feel secure entrusting your assets to those who have implemented these features.

Tick Erase disk and install Ubuntu.... you've already confirmed there's nothing else that needs to be kept on this computer, and that it won't have any other operating systems or working disks.

If you followed these recommendations to only install one single OS on one single disk, the boot menu you see (from GRUB) will have only one choice: Ubuntu, with the software you just installed, which will be selected by default after a few seconds whenever the system starts.
