Termux-app: Permission Denied

[dwrz]

Problem description
I appear to have lost permissions to files and directories in home, even though though I am their owner and permissions are set to 700.

For example, cd .termux will yield: bash: cd: .termux: Permission denied.

$ ls -lah

$ whoami
u0_a132

$ groups
u0_a132 inet everybody u0_a132_cache all_a132

$ chown u0_a132:u0_a132 .termux
chown: changing ownership of '.termux': Permission denied

Steps to reproduce
Unfortunately, I'm not sure. I opened up termux at some point and the theme had stopped working. When I tried to change the theme, I got a permission denied bubble, which prompted my investigation.

Expected behavior
Since I'm the directory's owner and permissions are set to 700, I expect to be able to set ownership and permissions, and to, e.g., cd into .termux.

You can't set ownership without root.

And if you can't cd into Termux's directories, then you greatly messed with SELinux labels. Use /system/bin/restorecon -r to fix them (as root !).

Thanks -- I'm not rooted. Is there anything I can do to confirm that?

$ su
No su program found on this device. Termux
does not supply tools for rooting, see e.g.
http://www.androidcentral.com/root for
information about rooting Android.

I'm not rooted.

Then I can't figure out what happens.
Try to reinstall Termux.

Go to settings and allow permission for storage👍
