I'm using Xubuntu 22.04.1, originally used 20.04 some months ago and then performed a dist-upgrade with no major errors. Yesterday, after updating and upgrading with apt, the following messages show:

Preparing to unpack .../archives/apt_2.4.8_amd64.deb ...
/var/lib/dpkg/tmp.ci/preinst: 4: dpkg-maintscript-helper: not found
dpkg: error processing archive /var/cache/apt/archives/apt_2.4.8_amd64.deb (--unpack):
 new apt package pre-installation script subprocess returned error exit status 127
/var/lib/dpkg/tmp.ci/postrm: 14: dpkg-maintscript-helper: not found
dpkg: error while cleaning up:
 new apt package post-removal script subprocess returned error exit status 127
Errors were encountered while processing:
 /var/cache/apt/archives/apt_2.4.8_amd64.deb
E: Sub-process /usr/bin/dpkg returned an error code (1)

After sudo apt -f install and sudo dpkg --force-all -i /var/cache/apt/archives/apt_2.4.8_amd64.deb the same error shows, even after sudo apt clean.

Also tried sudo dpkg-reconfigure apt, but it says:

/usr/sbin/dpkg-reconfigure: apt is broken or not fully installed

I have not found anything related to my problem. Although I could reinstall the OS, I would prefer to know if there's a solution to this

Error 127 is "command not found" which matches the next line, "`dpkg-maintscript-helper: not found`". That particular application is provided by the `dpkg` package. Check to see if `/usr/bin/dpkg-maintscript-helper` exists and is on $PATH. If not, reinstall that package.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
