Software updater changes permissions for some files in /var/lib/apt/lists/

On Ubuntu 20.04. The software updater (or something before that) changes the permissions on the files in /var/lib/apt/lists/. For example:

...
-rw------- 1 _apt root  24K  8月 28 16:24 packagecloud.io_rabbitmq_rabbitmq-server_ubuntu_dists_bionic_InRelease
-rw-r--r-- 1 root root 116K  8月 28 16:23 packagecloud.io_rabbitmq_rabbitmq-server_ubuntu_dists_bionic_main_binary-amd64_Packages
-rw-r--r-- 1 root root 116K  8月 28 16:23 packagecloud.io_rabbitmq_rabbitmq-server_ubuntu_dists_bionic_main_binary-i386_Packages
-rw-r--r-- 1 root root  11K  9月  1 21:17 packages.microsoft.com_repos_code_dists_stable_InRelease
-rw-r--r-- 1 root root 288K  9月  1 12:54 packages.microsoft.com_repos_code_dists_stable_main_binary-amd64_Packages
...

The software updater fails saying that it has no permission for the file packagecloud.io_rabbitmq_rabbitmq-server_ubuntu_dists_bionic_InRelease.

By the way, a few hours ago the permissions on the file packagecloud.io_rabbitmq_rabbitmq-server_ubuntu_dists_bionic_InRelease was -rw-r--r-- (and the ownership on root:root)

There are two options to fix that:

chmod 644 packagecloud.io_rabbitmq_rabbitmq-server_ubuntu_dists_bionic_InRelease
sudo apt update (that fixes the permissions as well)

But whenever the software updater makes a check, some of the files' permissions get changed and the software updater fails. Is there a permanent remedy for that?

What Ubuntu release are you using ? You tag your question with 20,04, but show bionic sources, bionic is 18.04 --- sources from mixed releases is bound to give problems. Please fix this.

I am using `20.04`. I could double check that. However, it also happened to other files like `security.ubuntu.com_ubuntu_dists_focal-security_InRelease`

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.
